I started a little LED upgrade to a small motorcycle headlamp assembly here. The factory unit is a LED assembly with an internal driver, however it puts out a paltry amount of light during night runs. I purchased a pair of Cree 12v XHP70.2 LED's, modified the heatsink to mount them in behind the lenses, and wired them(in series) to the driver. However when powered up, the system does not illuminate the LED's. They very dimly flicker at about 20-30hz.
Now I am no LED expert, but I am assuming that this means that the driver doesn't output enough current to illuminate them, so that leaves me having to power them via an external source. So I am here seeking advice on what drivers are available to run a pair of XHP70.2 LED's, 12-14V DC input. I don't need to overdrive these things at their max rated current, just looking for something that will drive them at an optimal level of output. Heck I suspect that even at 50-60% of their rating will be far greater than the OEM module that was in this headlight. I have done some google searching online, but I honestly don't know what is good/bad, what to avoid, etc, etc.
Preferably, I'd like to find something that has a fused 12V main input from the battery, and possibly a relay trigger that I can hook to the original low beam wire(either the switch or maybe the original driver) so that the hi/lo switching still works. I have to be able to seal it away from the elements, so that means I have to be able to either pot it or put it in a sealed enclosure. Having to build/solder it isn't entirely out of my capabilities(kit form) but I would need to know exactly what components to purchase and a clear schematic to work from(and maybe a few questions here and there answered) I do have to drive two of them, so I don't know what a decent amperage for these should be. Maybe 3-4 amps total at 12v?
Basically just looking for some input here on what to do or where to look/buy. Or should I buy the 6 Volt option xhp70's and work off a drive that doesn't 12V in put/6V output?
Thanks!
