Adjure's Ventura Highway custom headlight housings are die cast aluminum using precision dies. They are hand polished and flawlessly chrome plated for a show-winning appearance and are available with a smooth or radical flame finish. They feature the Phast-Lock system, a spring-loaded nylon rod that requires no special tools, to fasten the headlight rim and headlight unit, so there are no screws that disturb the fluent shape of your headlight. Also incorporates a rubber O-ring to keep water out of the bucket. Housings come with a 3/4" (19mm) bottom tree mounting block and are designed for use with a standard 7" headlamp unit. Housings are 7 1/2" (19 cm) over all length and 7 3/8" (18.7 cm) outer diameter.
