Halogen bulbs P21/5W - original quality for every headlight

P21/5W halogen bulbs are used for brake and rear marker lights. We offer bulbs from leading manufacturers such as OSRAM, PHILIPS and BOSCH - from standard models to versions with up to 150% more light or longer life.

Two-wire bulb - the weak wire (5 W) is for the indicator, the strong wire (21 W) is for the brake light. The pins are at different heights. The base is BAY15d, and the rated power is 21/5 W at 12 V.

Standard, brighter or longer-lasting?

Standard bulbs are the most economical and last a long time. The brighter series (such as Night Breaker, X-treme Vision or Racing Vision) illuminate further, but have a shorter life. The Long Life series are suitable if you ride a lot with the lights on.

Replace bulbs in pairs

We recommend replacing the bulbs in pairs - left and right. This way the light is the same in color and strength, and the second bulb will not burn out after a few weeks. Do not touch the glass with your fingers - skin oil shortens the life of the bulb.

Frequently Asked Questions

When should I replace my P21/5W halogen bulbs?

Apart from burning out, replace them if the light has visibly weakened or turned yellow - usually after 2-3 years of active driving.

Can I put in a higher wattage bulb?

We do not recommend - more powerful bulbs heat up the headlight and cables and are not approved for road use. Choose a series with more light at the same power.
