Will H4 LED bulbs work?

Buellxb Forum

Help Support Buellxb Forum:

Well, the H4 is a 3 prong connector because it's a dual filament bulb. The Buells use an independent hi-beam so the bulbs are single filament, and use a 2 prong connector.

That being said, it will probably work provided the plug will fit... Or you take the leads out and don't use the plug at all.
 
Sounds like I may need a couple of 3 prong to 2 prong adapters maybe?

thanks
 
Found a home for the H4's...in the Kia Rio..lol. Darn bright..put the H7's in the Buell..wow-big difference from stock. Ordered another set of H7's for the VFR. It takes 2 H4's and 2 H7's..crazy.
 
OK..follow up to the H7's. While driving around this evening I noticed that my high beam and high beam (blue light on dash) went out all of a sudden. Did the headlight mod as well several days ago. What happened? Bulb out..switch go..fuse?
 
Have you had any issues with moisture or rain? I think I'm going to order a set!
Thanks!

I have not but I think these fan type units are a stop gap technology, if you believe their ratings they will stay powered on for about 3.5 years continuous but I doubt fans will survive mud and water for that long. I figure if they need replacement in 3~5 years of normal riding that by then they will be all fanless and half the size.
 
I would check the fuse because I believe the dash light is wired before the headlights. So, if the bulbs were bad I would imagine the dashlight would still work. I also think would eliminate the relay because that is also not related to the function of the dashlight. Double check your work. You may have a short. I recently added led bulbs with angle and devil eyes, and after moving around existing wires I caused one of my hot wires to fault. I just used a tester and traced it back to the connector coming from my handlebar switch. I simply tapped into the good lead, bypassed the connector, and ran it straight to the headlight.

Was the fuse... Interesting that even with the blown light fuse, the low beams continue to work. Now the middle wedge light is back as well...only in low beam mode as before.
