Robbing LEDs from flashlights

Found an old LED flashlight laying around and I thought it would be perfect for my dome light. IF I can figure out how to install it. Anybody ever done this? Just need to find some self help interweb pages on wiring and electricity. I have no idea watt I'm doing in this area....

 

Buy an LED bulb, exchange bulbs in housing.... done!

 

Um, kind of missing the point. Trying to avoid buying LEDs because as you can see I already have some. Just not sure how to wire them into the existing dome light. Thanks, though.

 

An LED bulb is less than $5... but it's your truck!

 

I like to tinker with things. Again, you missed the point. Yes I could just buy some new LEDs but I thought it would be fun to play around with some that are just laying around the house.

 

Well your first hurdle is knowing how many battery's power that setup. The second hurdle is making a regulated voltage to power them and that's compatible with voltage from the truck. There is a lot of info out there. Adafruit, sparkfun, arduino are some places to look at for knowledge.

 

Thanks

 

Can't help but I hope someone is able to shine some light on this for you.

 

Just looking for something interesting to do. Not lifts or spacers or fancy air intakes or cool exhausts or sliders or seat covers or floor mats.... Just an idea.

 

What you did there, ah seent it.

 

Sometimes I get a little too amped.

 

Shocking.

 

I like to keep up on current issues, but I find this whole thread revolting.

 

OP, why not just put the batteries back in the flashlight and then duct tape it over the dome light. Problem solved.

 

Not really the route I was going for. But I'm sure you know where you can stick it....

 

If nothing else, my thread made me chuckle a few times.

 

@Bennoclarke How many batteries did that flashlight run on? Looks kinda like 3 AAA's? How many LED's did you want to use? Would also help if you could post a picture of the reverse side of the circuit board.

 

Give me a sec.....
