Light retrofit
04/19/9 at 15:29:20

Hey guys,

I am hoping to do a retrofit of a mountain bike light to gain better burn time out of the battery.

Right now, it's a 6v 10W halogen bulb, with a NiMH battery the size of a cigarette pack. I get a little over an hour of burn time, and would like to get more. The industry now produces LED and HID lights that get big burn times out of small batteries, but carry a heavy price tag, so I am hoping I can retrofit for a lesser cost.

Any thoughts on how to get started on this project?

Thanks

Dean Campbell

Well... HID means you're going with a 12v battery... and I don't think I've seen an auto kit that's under 35W. Perhaps there are people out there doing custom stuff on their bikes.

As for LED's... you're looking at a fairly high output LED, which is gonna produce some heat. Fitment of the LED to the housing may be an issue.

Perhaps there is already someone doing a retrofit kit for an LED to your headlight. Could be as simple as swapping a bulb.

You may be able to find a CREE direct drop in, but running into excess heat is a huge issue as doug mentioned.

I've emailed them to ask if I can retrofit either an HID or LED setup, and naturally haven't heard back. http://www.niterider.com/bike.shtml I'll pull the light apart over the next few days and see what I can find in terms of a number. The Halogen gets darn hot as well...
