High beam headlight issue

I've got a headlight issue, and I wanted to see if anyone else has run into this. When driving at night my low beam actually shines out further than my high beam. The high beam is definitely brighter, and provides more peripheral coverage, but it doesn't shine far enough out in front. Now perhaps I screwed up the alignment when I put the headlight cowl on, but if I did I would think that the low beam would also have a problem. Any ideas?

I think its an ellusion that its not as good
I have misadjusted my low beam on other bikes and had the same effect but driving slowly up to a road sign (green interstate signs seem to be the best for adjusting) I could see that the high beam was actually shinning further just not putting the light where I needed it.

Perhaps it is an illusion. I don't know. I could probably mess with the alignment again, and see if I can get it any better. I wish I had a headlight adjustment tool.

I noticed the same thing. When riding on a tree-lined road I noticed that when I switch to high beam, I get a lot less light on the road and more light up in the trees. When I took the 'Bird in for it's first service, I asked them to check the headlight alignment. I can't tell any difference. I agree that the reflective signs light up further away on high beam, but the road sure doesn't. The road gets darker. I guess I'm gonna have to put some accessory lights on it.

I had a weak low beam and an ok high beam... followed the advice of some folks on the forum and got a PIAA H4 bulb from my local auto parts supply.

Installed it in about 5 minutes and the difference is night and day. Powerful low and high - much better. A great $60 fix that could save your life if you live in deer country.

Just make sure you get a vibration protected bulb suitable for motorcycles - says so right on the box.

Drager that is a good idea. I will look into that. Thanks for the tip.

Greetings,

I have read lots of comments on the Tbird headlight... I agree with most that the headlight isn't as bright as you'd like... I don't think adjustment is an issue. I believe the issue is the light itself. DOT (USA) has requirements that Triumph has to comply with to ship their bikes to the US.

I've replaced my entire head lamp with an aftermarket... it was plug and play. Now it's more like a spot light...

Replacing just the bulb won't do it you have to replace the whole thing...

I'm puzzled as to why - how is the whole unit different?

I've ridden a number of times now at night with the new PIAA H4 bulb, and I have to say it is excellent. On low beam I illuminate signs 100 / 150 yards down the road and on high beam its incredibly bright - I get nothing but annoyance flashes from motorists if I have it on. I've ridden half a dozen cruisers this year, and ONLY rode with the high beam on because the lights were so crappy. I don't feel the same way at all with the Tbird, now that I've simply swapped out the bulb.

I have ordered Motolights and will install them on the front calipers when they arrive, just to 'be seen'. I don't have any illusions that they will actually light up the road ... maybe a bit to the left and right, but not at any distance.

I have to say that even tonight, as I rode in the dusk and then the dark, I'm very happy with the bulb swap I did.

I'm not sure why you would have to change the whole light assembly to get better results.

I gree with changing the hole thing!
In my case I modified the internals from an old headlight that was sitting on the shelf and installed them into the stock bucket.
The stock light just didnt seem to distribute light correctly, no matter what adjustment I made and felt that the cost of an upgrade bulb was out of line considering the bulb in there now can be had at any wall mart for less than half of the upgrade! and allows me no need for the high beam unless I want to go over 90miles an hour at night!
