KDX250 Headlight Bulb

(Click here to view the original thread with full colors/images)


Posted by: bajus22---------------------

Hey guys, I'm in the process of dual sporting my 1991 KDX250. I just installed the tusk enduro kit, which has a hi/low beam switch. Any ideas where to get a dual filament bulb that would fit into the stock headlight housing. I checked ebay, couldn't find anything there. Thanks.

Does the 250 use an H6M based bulb like the 200/220's do? If so, it should already be a dual filament bulb. If you can, take a picture of the base of the bulb (contact area) and another pic of the connector plate (contact area as well) that locks the bulb in place. You give me those two things and I can get you moving in the right direction.

OK will do.

Where did you get that Tusk Enduro Kit?

tusk seems to be a rocky mountain atv mc brand and tucker rocky brand

Yes, I got it from rocky mountain ATV. It's a real nice kit, relatively easy install. The hardest part was modifying the fender so it looked good, and finding a spot for the battery. The schematics were easy to follow, and everything worked like it should. Like I said, the only missing 'piece' is a hi/low beam bulb. The enduro kit supplied the switch.

I was thinking about putting a kit on one of my bikes. Ill have to look into that.

Here are the photos. I found a dual filament bulb. Now, how do I wire it to my hi/low switch?











Posted by: SS109---------------------

OK, in your first pic you see the contact plate. On the backside of it is where you need to solder on an additional wire. It sounds like you already did that, yes?

I also noticed you said you are running a battery. Are you running the headlight AC or DC?



Posted by: bajus22---------------------

Yes, I did figure out where to solder the wire, but where do I run it to, to get power. I tried splicing into the power going to the other filament, but all I eneded up doing was running both filaments at the same time (and yes I did go thru the hi/low switch). I don't know what I did wrong. If somebody could draw me a simple schematic, that would be great. And yes the battery I'm running is for the Tusk enduro kit, it is not recharged by the bike. Not sure if it's DC or AC (but I'm assuming DC). Thanks.

Are you using the Tusk wiring harness that was supplied with it? Well, if you take a look at RMATV's website they have .pdf documents showing you all the wiring. Take a look these and see if you can figure it out.

Yep, I had those, they came with the kit. Like I said, I'm not sure how to supply power to the second filament. When I got power to it, all I ended up doing was lighting up both filaments, whether I had it on hi or low. What wire (from the bike) supplies power to the second filament.



Posted by: SS109---------------------

The wire that fed power to the original filament should go into the switch. There should be three individual wires on the switch, BLACK, WHITE, and DARK BLUE. You need to hook the original power wire to the BLACK wire on the switch. Then run the WHITE wire to the low beam connector on the headlight and run the DARK BLUE to the high beam connector. It really is that simple.

Thanks.
