Asked in Ford Explorer
How do you check if ford explorer turn signal tail light bulb is out?
Obviously the easiest way to check if the bulb is out is to either turn on the signal and then go see if it is flashing. If it is the socket you are interested in. You can go buy a set of bulbs that look just like the one you took out and put a new one in. If you don't want to buy a set of bulbs and have a voltmeter and test if you are getting power.
