I am not a mechanic, however as an electrician it sounds like the running board lights are wired to the same relay as the interior lights. To check this, simply crank the truck, leave all the exterior lights off, turn on the interior light, then walk around the truck and look at the running board lights. If they are on then turn the interior light off and the parking lights on, check to see if the running board lights come back on. Depending on the make and model of the truck, I could be way off in left field and this info may not apply. uuummmm.....programing?
There should be a switch that has three positions, one position to have the courtesy lights come on only when doors are opened, another position to turn courtesy lights off completely and another position to have courtesy lights stay on continually.
Hey Humayun==It would help if you stated what kind of car you have. If you have automatic headlights there is a module under the dash that controls them and it is bad. On some cars, the lights stay on until the door is opened. GoodluckJoe
This is a standard feature on many modern vehicles now. The lights come on to aid you in getting safely from your vehicle to your door (aasuming they are pointing in the right direction). The lights should not be full strength and should turn off automatically in less than two minutes. Usually, if you wantthat door to door light, turn off the ignition first, before turning off the lights. If you don't want the light, turn off the lights first, then the ignition.
