Brighter Headlight

I find the headlight on my 2017 T120 is horrible. Any easy replacement to brighten it up for might riding?

Lots has been posted here. It’s the reflector causing this issue on the T120. The headlight from the T100 was the solution a couple of years ago but their price has gone up enough that the aftermarket is a solution now.

This may help. I installed a DIP Relay bypass. To summarize, it's a very small switch which allows the headlight to function in two ways.

When the switch is open, the head light operates normally. When you turn on high beam, the low beam is extinguished and the high beam filament is energized.

When the switch is closed, the low beam filament remains energized when you turn on the high beam, for great open road night vision.

Unless you have an LED bulb in it, that's a great way to overheat the headlamp.

When the WC T100 headlight was $200 it was a great solution. Drops right in, works great. Even comes with bulbs already installed. It might not be as desirable now that dealers want $400 for the same unit. It sure fixes the T120's weak, splotchy high beam that cannot be properly adjusted at all.

T100 headlamps do show up on eBay from time to time:

I went this route with a different LED bulb and although it looked better (a brighter, blue-tinged light) than the stock bulb the light cast off of the OEM reflectors wasn't noticeably better. The low beam was about the same (good) but the high beam was still useless with voids of darkness in the beam pattern directly in front of the bike. I eventually went with a JW Speaker LED headlamp. That solved the problem for me.

Clearview windshield, Triumph Cruise Control Kit DRL Type 2, Pazzo levers, JW Speaker Evo 2 LED headlamp, Booster Plug, Triumph LED indicators, 4 bar tank badges, chrome throttle body, clutch and inspection covers.

Do you need the extra "Mounting ring" to fit those JW's to a triumph? I'm not exactly sure what that part is for, even after reading the parts guide for it. I watched the motodemic install video, but he didnt mention it, though it looks like it might be preinstalled on his light.

Also wondering if the 8790 is coming soon or not, since its not in stock on their website, but it looks better than the standard one.

I found this one to be the best and easiest to install on the Triumph T120.
