I wanted to add more light to my 640 LC4 Supermoto but didn't want to pay for HID or add aux lights. I remembered reading about a headlight relay kit at WebBikeReview and rode down to Eastern Beaver to get a kit for my KTM. Jim Davis of Eastern Beaver was kind enough to help me get the H4 Weatherproof kit installed and it made a significant difference. I don't have before/after photos unfortunately, but it is by far the cheapest and best way to get more light out from the KTM. Jim showed me that the stock KTM wiring is pretty thin, plus the fact that the original headlight current is traveling throughout the whole electrical system means that the light is not as bright as it could be. The headlight relay kit uses a larger gauge wire to bring power directly from the battery to the headlight. This means that the headlight is optimized for light output. I chose to stay with the stock 55/60 watt bulb as I didn't want to take any chances with a higher output bulb. For those of you who want more light but don't want to go HID, or don't want to add aux lights, a headlight relay kit is a great way to optimize the existing headlight for maximum light output. Jim's a great guy and his kit works as advertised. Highly recommended. If I get a chance later this week, I'll take a few photos of the install so you can see how I have it set up. I need a permanent place for the relays (not as small as I'd like, or rather the KTM is rather spartan with little room for extras) so the install is not quite finished.
