A must when using mini style push button switches that are very popular amongst custom bike builders because their small dimensions. The same switches can also be found in PM and Ness "Petite" handlebar controls. Because they are so small these switches can not cope with the current flow, a relay must be used to switch from high beam to low beam and vice versa. Zodiac's High & Low Beam switch relay is designed the way Custom Bike Builders like it; it is small enough to fit in almost any head light as it only measures 1" x 1" x 25/32" (25 x 25 x 20 mm) and has mounting tabs to secure it. The "Beam Box" comes pre-wired and includes easy to follow installation instructions.
