Ok this might sound a bit crazy but bear with me...

My 3rd brake light bracket cracked below the carrier so my daughter and I put an led in the center cap of my spare, no biggie works great and looks better.
So my 11 year old asks if she can have the old brake light and unbroken part of the bracket to hang on her wall, and then says can we make it light up in my room? So I start thinking I don't see why not if that's what you want (she cant wait to take over my jeep at 16). So I figure no big deal, ill get a plug in 120 to 12dc transformer and wire in a switch. As I got to thinking and looked around I realized I don't know what amperage draw the light has to get the right transformer..

Does anyone happen to know what amount of amps or milliamps the stock 3rd brake light draws??

Thanks

Tony

Thanks guys

Transformer? Just use an old wall wart from any old electronic device that's below 15V. The lower, the dimmer.

If the bulb shows watts, remember P=VI, watts=volts*Current. Move it around and you get I=P/V.

If there is no markings, get a multimeter and measure resistance and use E=IR, voltage=current*resistance. That turns into I=E/R.

Even though I'm mathematically challenged.... that makes perfect sense
I know I have some old device around here I can use the plug in for..

Thanks for the help and ideas
