- The switch is located on the driver's side of the transmission and is a simple DIY replacement.

Is Your Back Up Light Switch Failing?
A faulty back up light switch is a common issue on Dodge Ram trucks. The most obvious sign of a problem is when your reverse lights don't turn on when you shift into reverse. Less commonly, the lights might get stuck and stay on even when you're not in reverse. If you have to wiggle the shifter to get the lights to flicker, it's a strong sign the switch is worn out or loose. On some later models, a bad switch can even affect the operation of a factory-installed backup camera or parking sensors.
Always Check the Basics First
Before you replace the switch, make sure the bulbs aren't burned out and the fuse isn't blown. It's a simple check that can save you time and money. You can also test the switch with a multimeter to confirm it's the source of the problem.
