I believe the OEM bulbs in the Triumph Light Bar are 35W H3's. I found that in a post somewhere here and added that to my "America Info list". 35W H3's don't seem to be readily available. 55W H3's can be had in probably every automotive store. Those that have used the 55W bulbs have reported no problems.
If you want to stick with the 35W bulbs, here's one source:
Light Bar Replacement Bulbs Once adjusted, it's really amazing how the light bar lights up the road ahead. At night if I ride with them on for a while then shut them off, I feel like I'm riding by 'moonlight' only!
