I'm thinking of doing a angel eye mod, but i wanted to know if its possible to measure the voltage that powers the angel eyes.

And what i would need in a device to be able to use that power and not give a error message.


Anyone know? radioshack volt meter or something?

My volt meter from harbor freight does the job quite nicely for only $5. But i would not try to power something else with them. I'd suggest using them for a relay and hard wire your hot line to the fuse panel.

I would bet it's 12VDC especially considering the stock bulb is incandescent. You can do any sort of trickery with resistors. I use a ceramic 25w/25ohm on my blinkers for my crappy LCI taillight upgrade (real connectors are being made for me now, thanks Bruce!).

The average draw of exterior bulbs on most cars I have worked with is 10 to 21 watts.

Be careful of relays if the power is significantly lower than 12VDC because your average 12V 5-pin Bosch type relay has a minimum spring rate of 8VDC, but anything close to that will make it flutter and eventually kill it. But if you do plan on powering something to time with the lighting of the halo's, like the other poster said, use relays - and be careful where you get your power source, because too much draw on another circuit might cause erroneous errors.
