Frequently Asked Questions


Q. Why are LEDs better than halogen bulbs?

LEDs (light emitting diodes) are more efficient, produce less heat, and last much longer than a standard halogen bulb. LEDs, on average, produce 10 times the amount of light of a halogen bulb, and LEDs can last up to 50,000 hours. A standard halogen bulb typically lasts only 2000 hours.

Q. Why won't the LED turn on after installing?

This is one of the most common problems when installing LEDs. Since LEDs are actually diodes, it only allows current to travel in one direction.  In other words, LEDs can only be installed one way. If the LED does not light after you have plugged it in, remove the LED, rotate it 180 degrees, and reinsert.

Q. Will the LEDs cause me to have a 'Bulb Out' warning on my dash?

No. At Precision LED, we've done extensive research on each vehicle package we sell. If your vehicle has "Bulb Out" sensors, your package will include CanBus resistor packed LEDs bulbs that won't cause a "Bulb Out" warning.

Q. Why do the LEDs look like they are still on after I turn off my vehicle?

There are two situations in which your LEDs may stay on after your vehicle has been turned off.

  1. If your vehicle has auto dimming lights, your LED lights will gradually dim before shutting off completely.
  2. Most vehicles, even when the engine is off, continue to send a small amount of current through the electrical circuits. This small amount of current is enough to turn the LEDs on to a very dim level. Don't worry though - this won't drain your vehicle battery since the same amount of current is traveling through the circuit whether you have halogen or LEDs.

Q. I have auto-dimming interior lights. Will Precision LEDs work?

Yes, LEDs will work with auto dimming lights and are not damaged by this type of lighting system.

Q. How do replacement parts affect my vehicle’s warranty?

The short answer is they don’t.

The long answer? It’s against federal law for a manufacturer to void a warranty for use of an aftermarket part. The Magnuson-Moss Warranty Act, enacted in 1975, makes it illegal for auto manufacturers to void a warranty simply because the owner of the vehicle adds an aftermarket product to a vehicle. The law states that unless the manufacturer can prove the problem was caused by an aftermarket part, they have to repair the vehicle.
