I'm looking to make a conversion for a custom saber with LED and sounds (hilt bash and clash)
I went with the Hasbro Kylo Ren series from the blade builders collection with the extra dagger at the bottom. I want to install a more powerful LED maybe a cree, something that outputs more lumens. I measured the voltage output from the LED stack off the board inside the Hasbro toy and it only outputs 2-3v. Is there anyway I can drive an LED that takes a higher output without fizzing out the board? Also it is controlled by a microswitch mounted on the board with a kill switch seperate from it. Any way to bypass the microswitch?

Many thanks from a newcomer
