Dual-filament bulb for tail and brake lights, supplied as a pair.
The UNITEC P21/5W car bulb is made for the rear position and brake lights of 12 V vehicles. Each pack holds 2 bulbs, enough to replace both sides of the car at once.
Tail and brake light bulb P21/5W
The P21/5W designation covers combined rear lamps where a single bulb serves both the position and the brake function. Operating voltage is 12 V, the standard for passenger cars.
Two bulbs per pack for both sides
Replacing left and right together keeps both lamps matched in brightness. The spare can simply stay in the car, which is handy since several countries require carrying replacement bulbs.
Tool-free replacement
The bulb twists into the standard rear-lamp holder and needs no special tools. Handle the glass with a clean cloth to keep fingerprints off the envelope.
