Manage to convert this halogen head lamp to LED.
1) You'll need to create a lens cover out of plastic or lexan. One in picture is plan plastic sheet. As the previous cover was from the bulb itself.
2) For details on the the light housing going into the BLT housing click here. It's steps one to three from my Easy XM-L build. the only difference is I attatched the driver to the back side to the Cup 2 Plug. You'll have to determine which wire coming from the BLT set is positive and which is negative. Don't know if they're made all the same but on my set positive was on the right when looking at it from the front. After that all you need to do is solder the wires to the driver, "+" in the center and "-" is around the edges.
3) Once the driver is set, test to see if the light is working and carefully push everything in. I placed drops of silicone to the contact points to protect it from shorting.
4) Once it's sealed, attatched to you helmet and go out at night and ride.
I know these were popular back in the day, so if you still have them laying around collecting dust maybe this can help you recycle them. So for about $20 you'll have yourself a high power and bright headlamp.
