Description
The Capless Bulb (product no. 37556) features a 501 base and is commonly used in side lights, tail lights, and some internal caravan lighting. Designed for reliable, long-lasting illumination, it ensures clear visibility and enhanced safety on the road.
Capless bulbs are easy to install—they connect directly through their glass base, eliminating the need for a metal cap. This design makes them more compact and helps improve electrical contact. In contrast, traditional “capfull” bulbs have a metal base and can be bulkier or harder to fit in tighter spaces.
A convenient replacement bulb to keep your lighting system bright and road-ready.
