LED light bars come in a variety of sizes, shapes and beam patterns. Used mainly for off-road driving, LED light bars have become extremely popular and as a result they are being used for much more than just off-road driving. Smaller LED light bars are used in conjunction with your driving lights when driving through poorly visible roads. LED pod lights are also used as fog and back up lights providing a substantially higher output of light compared to stock lights. LED light bars can be mounted above the roof of your truck, behind the grill, or beneath your front bumper.
