This light operates on DC voltage only, if you have an Ac powered headlight you will also need the rectifier below.

Most all street legal bikes are Dc powered, the exception is the KTM EXC 250/525/530 carburetor equipped bikes and most other dirt based dual sport bikes.

WR250r is a dc powered bike

Please note that for dirtbikes we recommend our 3600 Lumen version as it creates a better off road beam pattern.

Rating Great product
Installed on my 2005 screamin'eagle electra-glide. Easy, no issues. The boot had to be discarded. The improvement in visibility is huge, especially the high beam. Lights up far ahead plus the sides of the road. This is a fantastic product. Highly recommended.

Rating Perfected VW Mk4 Jetta Conversion w/OE Fogs
I have posted all steps necessary for conversion on VW Mk4 Jetta with OE fog lights on VW Vortex. I'm very happy with the end result. The improvement in quality and quantity of light compared to good halogen bulbs is significant, at least double or slightly more in my opinion. H4 plus H3 LEDs from Cyclops are a great upgrade for the VW.

Rating Big Upgrade
Installed on 1997 BMW R1100GS. the BMW doesn't use the standard H4 style clip, so a little more retrofitting was needed. Once everything was installed and wired up, no headlight adjustment was needed. The light output is fantastic and the color spectrum is great. Well worth the time and money.

WOW! Best money I have spent this year. Tested this product the other night and it met and exceeded all my expectations. Did have to modify my weather boot over the light enclosure to get it over the fan but that was easy. Was worried that the light was a little high especially on the sides but not a single car flicked their high beams at me as I passed them. On the trail I could see everything way in front and on the sides as well. Highly recommend this product. Enjoy.

Great product, very easy to fit apart from my headlight bucket being a very tight fit for all the parts (not the bulbs fault). Yo can even unscrew the bracket so that you can slip over a tight rubber seal without cutting it. So much brighter! Quick delivery.

81 BMW R65 Far superior to any other bulb i have tried. Instillation was easy, just a bit of fiddling to get the clip wire that holds the bulb in on properly. It fit in the headlight bucket well. most happy
