Hi all. Ive been trying to find info on these lights as I've found one for a good price. All the info I can find has to do with upgrading to LED's which I don't want to do as I wish to keep it as an incan. So I see they use cr123 batts and rcrs will flash the bulb. Even Lifepo4 cells seem to be a problem even with their lower voltage. Any rechargeable solution? Also I've seen it recommended to bore out the body and use 18650 cells. But that's only 1 3.7v battery when it need 2x3v batteries. Wouldn't that greatly underdrive the bulb? And lastly I've found other assemblies to install but that could get expensive when needing to change incan bulbs when they need it. Where to find just $3 or so bulbs instead of entire assemblies? Like just replacing to a factory bulb?
