I think the stock headlight on my T100's are less than adequate. I have installed brighter bulbs and that does help. My opinion is the reflector is the culprit. If I adjust the low beam properly; the high beam is only useful for spotting birds and airplanes. If I adjust the high beam properly, the low beam is only good for lighting the area immediately in front of my tire. I have reached a compromise in adjusting that makes both beams do somewhat of what they are supposed to do.

Someone posted on another forum about converting the stock head lamp to a sealed beam. Several folks have done this mod and posted that they are satisfied. Here are the instructions.

Any H6024 7" halogen will work; but it doesn't have the city light (parking light). The city light feature is not necessary anyway since you can't turn off your headlights in the US anyway, so just unplug that and tuck the connector away. A H6024 will cost about $15 at any aftermarket automotive supply.

Best of all it is an all-glass sealed beam, easy to clean and won't fog up like some of the composite lamps.

It actually isn't hard to install the sealed beam, I have one on my Speedy right now. For me it was a matter of pride, since we make them I thought it was important that I have one on my bike. The composite lamps are actually made to the same dimensions as the sealed beams, because they have to work in the same applications. The sealed beam has three lugs on the back and the composite has three metal tabs in the same location, either way those three lugs or tabs go under a clip on the chrome light ring to position the light correctly. There is a triangular wire clip you have to wrap around the back of the reflector that clips into the chrome ring also, it can be tricky finding the right location so that all of the points of the clip can tuck into the ring without interfering with the lugs (just pay attention to how you take it off the first time). The contacts are the same so no problem with the plug. Just tuck the city light plug away. The H6024 is a 1 degree down 3 degree right lamp in low beam, and straight ahead in high beam. You will be amazed at how much of the countryside is lit up in high beam. Buy GE if you can, it's all US made.

I have done this and am pleased with the results.

I converted my T100 to a sealed beam this evening. I had tried it before and changed it back for comparison. Then I just left the stock setup in place since I don't ride much at night. Last night I rode my TR6; the first night ride I have done with it. That old headlight was better than the stock headlight on my T100 - which isn't necessarily saying much. My high beam on the had T100 burned out and I decided to go back to the sealed beam rather than replace the bulb in my stock set up.

I took it out for a brief ride after dark and the difference in the light is astounding. With the stock setup. getting the high and low beams aimed is a compromise. If you get the high beam aimed right, the low beam illuminates your front fender nicely - and little else. At thirty miles per hour, you are over driving your headlight on low beam. If you get the low beam aimed properly, the high beam becomes an effective search light - great for finding racoons in trees or flying squirrels. I did finally get mine fairly well aimed; but the low beam was still too low.

A sealed beam changes that. High beam lights up the road ahead nicely and the low beam still lets you see where you are going at speed. It works like a headlight should work. The sealed beam bulb is 65W/55W - the same as the stock bulb. I installed a Sylvania CoolBlue halogen. I had running an 85W/65W halogen bulb. I get more light with less wattage. The head light number is H6024.

The pattern is different and, at first, it feels and looks strange. It is an automotive headlight. But you get really good light down the road and just enough to the sides. The high beam points straight ahead. The low beam is one degree down and three degrees to the right of the high beam. The sealed beam unit is less expensive than a holgen bulb for the stock unit. I paid $18.09, including 7% sales tax. A holgen bulb is $23.00 - $27.00.

I have been told that a motorcycle specific sealed beam is even better.

If you don't like your stock headlight, try a sealed beam.


Carl this is very interesting. As I also hardly ever ride at night nowadays I have never really given this much thought. Also when I have ridden at night it has always been in an area where there is plenty of lighting from the street lights. At one time I thought of putting on a pair of riding lights but never got around to it as it was more for the looks than being a practical solution. Thanks for this information. - DaveM


Dave, I have to ride six miles (9.7 kilometers) south to find the first streetlight, sixteen miles (25.7 kilometers) north, or 22 miles (35.4 kilometers) west. I need a decent headlight. - CarlS


The '05 Americas came with a sealed beam, but it was as bad as the other stock headlights. Low beam was a pathetic, downward aiming, yellowish light. I put in a Sylvania Silverstar, about $20 at Discount Auto Parts. For quite a while after that would often forget to hit high beam. Some have said that auto bulbs wouldn't last as long due to the vibration. I've had mine for 8 or 10 thousand miles. A bike-specific one would probably cast a better pattern, though. - Lonzo


Lonzo, the Sylvania CoolBlue is the next step down from the SilverStar. I couldn't see much difference in the specs for the two and since I did not know how well it would work, I got the less expensive one. When I have to replace the bulb in Mae Lyne's T100, I'll try the SilverStar. I got mine at Discount, too. I was really tring to find a GE because GE's are American made. But Discount doesn't carry GE and I would have had to go to St Augustine to find the GE.

As far as vibration goes, my T100 vibrates less than some cages I have owned!! I think you can find a motorcycle specific sealed beam at Harley shops; but I hear they are pricey. You are right about the low beam. I can actually ride using it with this sealed beam,

This was cheap mod and an effective one. - CarlS


I installed an H6024 sealed beam in mine last night. Conversion was real easy and it works fine. Bulb is a Wagner, and it says made in USA. Got it at Car Quest and it only cost $9.99. We'll see how well it holds up. Can the vibration on a T-100 be worse than a 70's anything cage??? I think not. Thanks for the tip, Carl. - Fuzzy


You are welcome, Fuzzy. Let us know what you think of the sealed beam. - CarlS


Sealed beam works well. No problem with installation at all. Side illumination is good and I am much more confident at highway speed. When compared to the stock light, I am surprised the stock light would ever pass DOT muster. - Fuzzy


Thanks for the feed back. I had to ride in the dark in the fog Thursday morning leaving about 05:30. It did much better penetrating the fog than thn the stock headlight did. I try to avoid riding in the fog as a rule. - CarlS


Changed my Silverstar sealed beam with one of these (the link is no longer valid). I do quite a bit of night riding. The Silverstar light pattern was great when riding straight, but less than ideal on dark, twisty roads. The beam pattern consists of a rectangle right in front of you, and a long, narrow beam straight ahead. I think its because its an auto bulb, designed to be used in pairs, and not leaning in turns. This ebay light (I opted for the 100 watt bulb) seems to be much better so far, we'll see how long it lasts. Its not a sealed beam, takes an H4 style bulb. - Lonzo


Lonzo, now that you've used the Autopal headlight, what do you think of it?

How does it compare to the stock headlight and the sealed beam? Which bulb are you using? - CarlS


I like it. The hi-beam isn't as focused as the Sylvania. It lights up a broader area. I got the 100w blue. Lo-beam is plenty bright, too. - Lonzo


Thanks for the update. I may give it a try. Having ridden my T100 at night with the sealed beam and Mae Lyne's at night with the stock reflector, I can attest that I like the auto sealed beam much better than the stock beam - especially the low beam. - CarlS
 
With the "cat-eye" double lamp on my Trophy, it's impossible to change to a sealed beam.

I do have a headlamp adjuster knob that I can turn and adjust the height while I'm riding (stock on Trophys). But the lights are still lousy no matter where I adjust them to.

In talking with other Trophy owners from all over the world, it seems that it was the American owners who complained about this while Euro owners did not. After much discussion and exchanging of photos, it turns out that the bikes sold in the USA have different lenses with different focal points (probably due to some obscure USDOT law).

The remedy for American Trophy owners was either to spend a fortune on buying replacement lenses from a UK supplier (not real easy to change-out) or upgrade to PIAA or OSRAM halogen bulbs (which doesn't really solve the problem but improves it).
 
With the Bonnie family, I think it is the reflector rather than the lens; but it could be the lens. I know the Lucas headlight on my 68 TR6 is better than my stock '03 Bonnie headlight. I run high beam all of the time in less I meeting a car close up up on a two lane, unlighted road, then I use dim.
 
It would be interesting to do some research and find out if Bonnevilles in the USA and Europe have completely different headlamp assemblies...possibly a combination of different lenses and reflectors or just different lenses or reflectors.

It makes snese that this could be the case since I know a guy that imported a euro-spec Volvo and one of the things he had to pay to change before they would release the car at the port in New Jersey was the entire headlamp assemblies (and disconnect the rear fog lamps).

When I brought my Porsche in I did not have to disconnect the rear fog lamp. I already had US spec headlights.

Someone slipped-up then!

My MINI Cooper originally had one section of the tail lamps non-functional. It bugged me to see that section dark so I began reading-up on message boards to learn that the dark section was the rear fog lamp section and in Euro-spec MINIs, they have a switch on the dash.

To my surprise, when I opened-up the tail lamp assembly, I found the sockets were there and there were even bubs installed, but not being used.

I bought a toggle switch to match the others from the MINI dealer and installed it in the blank spot on the dash where the Euro-spec cars had them. I then ran wiring back to those unused lamps and jumped power from the parking lamp circuit. I now have rear fog lamps!

I also read of some US owners who simply jumped power to those unused lamps from their brake lamp circuit and now use them as ultra bright brake lights.

The fact that they come into the USA disconnected though causes me to believe that they are not approved for use in the USA.
 
You could be onto something there. :y115:

Not to go too far off-topic (yeah right....) but this brings up another pet peeve of mine. There should be a very strict law heavily enforced which fines people who ride around in their cages with their fog lamps turned-on when the weather is perfectly clear. Kind of like those laws where you are required to turn-on your headlights when it rains except in reverse.
 
I concur 100%!! They are not driving lights. The driving lights on my Porsche went off when I switched to low beams. If I had them on, the fog lights went off when I switched to high beams.
 
I will honestly tell you that the H4 Hallogen is much better than the stock 12V bulb. The sealed beam 7" headlight is much better than the H4. The ultimate is the HID Xenon dual light system which is a single light with a hi/lo function.
 
Thanks for the tip. I will have to check this out. :y115: I assume you replace the stock head light bulb with this. The problem with the stock headlight is the reflector. When the high beam is properly adjusted, the low beam is aimed too low. Does this bulb solve that problem? Is the low beam aimed the same as the high beam?

I think the older ROUND bulbs don't seem to have that problem. The later "pre-focus" oblong bulbs do that for me. I thought pre-focus sounded like a "good" thing, but I guess not!?
