DC Voltage Only
If you have AC powered headlights, you will also need the optional rectifier shown (see product options to add one). Most street legal bikes are DC powered, exceptions being the KTM EXC 250/525/530 carburetor equipped bikes and most other dirt-based dual sport bikes. The WR250r is a DC powered bike.

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.

I used those on my 2011 BMW GS Adventure and it fitted perfect and the light is amazing. Now I am looking another one for 2017 Harley Davidson Street Glide.

Excellent leds that will loght up your way
I just retrofitted this H4 3800lm led to my 2007 BMW F650GS. The result is brillant. The difficulty was to find a led that replicates the regular filament pattern and the cyclops H4 leds are excellent in this respect with a sharp cut-off of the beam pattern. The quality of the led looks also great especially when compared to cheaper H4 leds in the aftermarket. The color of the led which has been lowered to 5500k gives also a better visibility at night than a 6000k. In other words this led is great and I will definitely recommend it. Enjoy and stay safe!

LED Bulbs for 2016 Triumph Tiger 800
Purchased the 3800 H4 LED bulbs for my 2016 Triumph Tiger 800. The install was very easy, especially after watching a youtube on the install process. The result versus the stock bulbs, is no comparison, well worth the $130 for the set of bulbs. Thank you, Jeff

3800 H4
I ordered the 3800 Lumen H4 bulbs for my 2015 Triumph Tiger 800 XCX about a year ago. Huge improvement on both low and high beam. I just called and asked about the 7000 Lumen lights, and instead of trying to up-sell me, they gave me an honest run down of the differences between the 2 lights. The 7000 is has a much brighter low beam and not as much of a noticeably brighter high beam. I'm fully happy with my low and high beams, but if low would have been similar and high would have been much more noticeable, I probably would have upgraded because you can never have too much light on the gravel and dirt, but where I needed it, the upgrade wouldn't have made a big difference. I did order headlights for my truck and wife's car. Great products and people.

7000 lumen H4
Easy install (allowing for everything else you have to get out if the way first), perfect fit. Used the low beam spacer as suggested, good call. High beam blazes like an aircraft landing light, awesome. Far better option than sealed LED headlights costing three to four times as much.

Suzuki 2014 Vstrom 650 (DL650A)
Once I learned on the first bulb the second one was very easy to install. Had to trim 1/8 to 1/4 inch off rubber boot. Then all was just plug and play. Cool white light (slight bluish tint). Way brighter than OEM. I bought the 3800 lumens H4 LED headlight bulbs. I can slightly hear the fans on the bulbs with just power on. Can't hear the fans after the engine is running. As a side note, also replaced the turn indicators with 1156Amber led bulbs and the stop/ tail light with 1157Red bulbs. Highly recommend Sylvania Zevo series. Bought them at an auto parts store. Slightly brighter than oem bulbs.
