<strong>5.</strong> The latest craze in off-road lighting is LED, light emitting diodes. LEDs are small semiconductor plates that emit light when electricity is run through. Efficient, vibration-resistant and lasting much longer than halogen or HID, they make great off-road lights. We installed this Baja Designs LED driving light, which houses 18 individual lights, on the roof of our buggy with a Mercenary Off Road light bar. On either side of the LED are two PreRunner internal ballast HIDs also from Baja Designs.
