08 led upgrade

I am trying to install leds on my bike, I am confused why it could run with 55w halogen but 35w leds don't work, any ideas or suggestions?

You are going to have to tell us more than that. As much as I don't like the idea of LEDs, they are usually plug 'n play.

What LEDs are you installing, did you cut any wires, in what way are they not working, are they H7 LEDs, how many contacts are on the bases, are they internal or external fans or no fans, etc.

You can't post pictures until you have 15 posts so, if you do have pictures that could help, you can e-mail them to me at the address in my signature block.

They came from Ebay, eBay item number:372616085006, cree, 35w, 6k headlamp h7, internal fan, two prong, plug and play. I installed them and tested without running the engine and they worked, once I started the engine they stopped working and would not start. I tested them on my car and they didn't burn out. My gold wing (cafe in the making) has a plug and play light so I figured it would work here too. Thank you for your quick reply.

(cant post links till 15 either)

The info says they are not polarized, so that's not a problem. The only thing I can think of is that the fuse blew for some odd reason. Check the fuse under the seat.

Do you have a voltmeter or a test light? If so, you could also check for +12v at the headlamp connectors.

Do these require the use of the OEM bulb spacer? That's sort of a non-problem related question; just gathering info. I noticed that those are advertised as fitting the Sonata and wonder if they are JIS H7 or Euro.

There are two versions of the H7 halogen bulb, and the difference is in the prong spacing. There is the European version, with prong spacing at about 11.5mm and the Japanese version with prong spacing at about 16.5mm. The Gen 2 harness has a Japanese connector and Kawasaki uses an adapter so that the world market can use the European bulb.

Forgot to add that the bulb spacer is the black dingus in the photo above.

I'm getting ahead of myself, but I wonder how much current these things really draw. The LED shouldn't pull much, but the fan says it delivers 7CFM. Never heard of H7 LEDs blowing fuses, though...

Fuse was good, maybe it the bulb itself, 9v-32v, watts up to 600w. Stupid technology, out smarting me. Thanks for your help I'll update when i get better bulbs.

But they worked after you installed them (with the engine off) and you put them in the car and they worked, right?

Do the original halogen bulbs still work?

The Low Beam burned out. Yes the lights worked while off but once the engine kicked on they stopped. It may be that they are variable voltage and wattage, I will take my car bulbs and try them. Update a little later tonight. Spacer thingy, yes I have and am using the black dongle.

Yes, the bulbs from my car worked in the bike. 12v/55w so maybe a led with a diode?

Plus the original that didn't burn out.

No diode should be necessary that's not a part of converting to LED, be it headlight or turn/stop lights.

If they work in your car and normal lights work in your bike, I can't see any reason why they wouldn't work on the bike. I guess the only thing left is to reverse the connector so that the polarity is reversed on the LED bulbs. It sounds really weird that that would solve anything because they are supposed to be non-polarized, but I'm out of ideas.
