Rep Power: 350

ive got an autometer ultralite a/f ratio gauge and was going to install mabey a fuel pressure gauge or something like that but i was wondering if they light up when you turn your headlights on or if theres a seperate switch or something. if not im going to buy the series gauges that i know for sure light up.

They come with lightbulbs and the colored condoms and you can wire them to your dash lights. The AF gauge is not back lit because there's no room in the gauge for the bulb. All you get at night is the sweeping LEDs.

I wired mine to the 12v outlet harness.
Light comes on , When you turn on the car.
