## Description

Tek Automotive 380 P21/5W brake and tail bulbs are designed for vehicles that use a BAY15D base with staggered pins. This twin pack contains two 12V 21/5W dual-filament bulbs, allowing one bulb to operate both the tail light and brake light functions for correct rear lighting performance. The staggered pin design ensures the bulb can only be installed in the correct orientation, preventing incorrect fitting and ensuring the brake and tail light circuits function as intended. This provides the correct brightness levels for running lights and braking, improving safety and visibility on the road. All bulbs are fully E approved and road legal for use in the UK and EU. Manufactured to high quality standards, they deliver reliable light output, vibration resistance and long service life for everyday driving and maintenance. This twin pack allows you to replace both rear bulbs at the same time for balanced brightness or keep a spare on hand for quick and convenient replacement whenever needed.
