So I tried driving around with the LED bulbs installed in my tail lights and when my lights were on my acceleration was cut down dramatically. I have an intake and headers installed and sounded like they weren't even installed under acceleration. When I turned the lights off under the same acceleration off she went and I could hear the power again. How can LEDs do this?

Also with the lights off when I press my brakes my parking lights, corner lights, and gauge lights illuminate; as if I turned my light switch on to the 1st light setting. Do LEDs have the power to do all this to my car?

 

they could be draining your voltage do you have equalizers installed on the tail light wiring? and are you getting a bulb out warning when lights are on?

 

There was a recent thread about LED brake light bulbs making the cruise control inop, so I'd start looking there.

Sort of a separate question - does the power seem OK until you get well into midrange rpms?

Jreed-I don't have loaders installed and did have bulb out warning. (Past tense cause I put my old bulbs back in).

Norm-thanks Ill look into that and I would say it was ok up till about 3,000 rpms or so
