The Rainbow Strobe is a small cage assembly that slips over an H-4 style halogen bulb, creating a colorful pattern within the headlight. Although the beam is, for the most part, unaffected, some blue, green, and red coloring occurs. Installs with ease. Check regulations for suitability in your area. For use with H-4 halogen bulbs with three prong base.
A single headlight vehicle can use either a left or right side strobe.
