Hi Mal and Karen

” The new 10.0 is now available in two options. The original 38 watt 5000 lumen version and now a new 10,000 lumen 76 watt version.

Both offer the same low beam cutoff pattern that is so very important. The difference is the 10,000 version runs all 4 emitters when on high beam.

The 10.0 is applicable to most all H4 applications and is a upgrade from our original 3800 and 7000 H4’s

It is better in every way. Metal bases, better focus and better thermal management.

It will fit the DR, DRZ, WR250R and pretty much any H4 application ”

Best Regards Darryl

NOTE – fits Honda CRF300L does not fit the Rally version.

NOTE- if fitting on the KLR250, place the boot under the bulb fan, to do this cut a small hole to allow the bulb stalk to pass through, failure to do so will cause premature failures


DC Voltage Only
If you have AC powered headlights, you will also need the optional rectifier. 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.

NOTE – we are an online store catering for a small select range of old school Japanese bikes as per the opening page of the website, we have some additional bulbs because people request them, we are not technicians or auto electricians, please YOU need to know what bulb fits your own bike !
