On any light precise focusing is essential, and you dont always get it, particularly with cheap globes.
Phillips Halogen H4 Plus 50 and Plus 100 globes are made to tight tolerances and if you get a full 12.6 volts to them and you have a good reflector will give all the light you need.
Eastern Beaver make an excellent, easy to fit heavy duty wiring harness which makes certain you have full power to the globes.
If you dont get sufficient light with a EB harness and a plus 100 globe the reflector is at fault and a LED globe wont help much.
Anyone remember HID lights?
