Headlight

Rode my bike at night for the first time yesterday evening. Horrible! Firstly, the headlight was way out of adjustment so it only illuminated the road about six feet in front of the bike. Secondly, the beam is skewed so it's about 15 degrees off the horizontal and, lastly, there was a power cut (not all that unusual where I live) so there was no street lighting. With an overcast sky and no moon, it was as black as a badger's arse on the back roads home (and on top of that I had my lady on the back). There were a lot of potholes, uneven surfaces, sand, pools of water and other obstacles to be navigated on the way back and it was no fun at all. At one point I think I was overtaken by a two-year who was learning to walk but it was too dark to know for sure. So I need a better headlight.

I've perused all the threads relating to replacement headlights for Bonnies and have narrowed it down (I think) to two options that people are recommending. Either the Hella H4 or a Cibie unit (and /or Sylvania H6024 bulb). Now, we drive on the left where I live so the US DOT non-compliance issue is not a problem but it seems that these two options do not fit all bikes (from what I can gather it seems the headlight housing changed around 2010 on the EFI bikes). I have a 2008 T100 EFI 50th Anniversary Limited Edition.

Has anyone fitted one of these options to a similar model and, if so, which do you recommend (or if you have alternative suggestions I'd welcome them)?

Until I get this fixed, won't be riding in the dark again

Not specifically for the T100 2008. Misaligned lights come from a few different things.

The H4 bulb is supposed to be very standard but I have seen aftermarket, typically LED bulbs with the LEDs not quite at the right place. Their driver and heat sink take room too, and they may well be pressing on the reflector and bending it out of focus. If you are using an LED bulb, try reverting to the halogen one.

Some had simply left the bucket looking way up or way down, and the beam simply missed the ground. They could adjust up and down by easing the supporting bolts and pushing the bucket up or down.

The more worrying thing is the 15 degrees slant in your low beam, I assume left to right, not up or down. Maybe open your bucket and check that the reflector is set correctly: here is a tab near the top of the reflector assembly that must match a slot in the bucket. If it does not, you may try to put it right --it nothing has been broken.

Last resort, some find modern WC T100 headlight assemblies to be simple and nice, offer a good light pattern and could be a drop-in replacement (anyone to chime in on this?).

Enjoy your Bonnie.

Cheers

First upgrade the wiring with a direct-to-battery relay harness. Eastern Beaver sells them ready to plug in.

You can adjust the side to side with the screw in the headlight ring. I put a H6024 into the stock 2005 T100 headlight. It fit fine except that there was no longer a parking light, no big deal.

Ride safe,

Quentin

I've a sealed beam halogen bulb in mine which works ok. The first time I went out and came back after dark was when the realization that the light was pointing so far up it could have been an airport searchlight. Luckily the stretch of road in front of the house is straight and has a reflective road sign about a 1/4 of a mile away. I aim it at night using the sign as a reference point.

I replaced my stock Scrambler size (5 3/4" vs 7" on T100) headlight bucket with aftermarket 7" bucket and added a Phillips LumiLED 3000 Lumens bulb with copper-ribbon flexible heatsink and separated power supply (made it easy to fit in the bucket). Huge improvement! Light is so white/bright it makes me stand out even in full sun light...important in urban traffic.

So, you should look at replacing the bulb in your stock bucket with something similar. Changing out the bucket can be difficult to find the right fittment and you will still not be getting LED light output from Halogens.

Thanks for the advice everyone. I've adjusted the headlight correctly now but it's still not giving enough light for my liking for some of the dark roads/tracks I have to deal with where I live. Am going to fit an upgraded unit when I've sifted through all the advice in the headlight stickies.

H4 LED

Hi John,

I got this from out East, close to you. Ream out the plastic reflector hole a little (file or sharp blade) and it pops right in.

I just hit up Daniel Stern on the subject:

Quote:
Put in a very good American-made DCX headlamp lens-reflector unit ($139), pic attached, which compared to any H4 lamp will give a large improvement in terms of more light within the beam, a wider spread, and longer down-the-road seeing distance, with better lighting even when you're banking into turns. You'll need an adaptor pigtail to be able to plug this lamp into your bike's socket, that adaptor is $17. Put a cherry on top by installing a premium bulb, which I don't sell but this is the one: https://www.amazon.com/dp/B00U1OLOP0/?tag=2402507-20

The reason why this lamp is a considerably better pick is that the H13 system uses the entire reflector surface area to gather, amplify, and focus light for the low beam, while the H4 system uses only half. You can see this for yourself if you turn on the low beam and look at the operating headlamp; the lower half of the reflector is dark. The beam pattern of the DCX lamp is very well suited for motorcycle usage; it is symmetrical and does not have a super-sharp low beam cutoff which would tend to make your seeing distance go to zero when you bank into a curve. Note the new lamp does not have a provision for the parking light function presently provided by the miniature bulb located a short distance away from the main bulb in your headlamp. That function and that bulb are superfluous in North America where motorcycles are not required to have a parking lamp function because the headlamp is illuminated whenever the engine is running. The parking lamp function is a (mostly obsolete) requirement in certain European countries; Triumph just chooses to equip all their bikes regardless of destination. When you're in there replacing the lens/reflector unit, simply fold the parking light wire back and tape it off.

I was advised yesterday in France that LED headlights are forbidden here as they tend to blind incoming traffic.

It makes sense. They do provide a very sharp illumination but the light pattern (a spectrum of a few separate colors) is certainly likely to even actually harm the onlookers' eyes, and cause even permanent harm.

If you go on and for an LED headlight, be very sure the pattern cuts off the low beam sharply.

I would rather stay with a halogen bulb in fact. (I did in the end)
