LED Bulb P21W BA15S – Versatility and reliability

The P21W bulb and its applications

The P21W bulb uses a BA15S bayonet base, with a single filament. It is one of the most common references for secondary automotive lighting. It equips many vehicles for different functions, depending on the model. Switching to LED provides instant lighting, 80% lower consumption and a lifespan exceeding 30,000 hours, compared with about 1,000 hours for halogen.

Choosing the right P21W LED

Check that your vehicle does indeed use a BA15S base (15 mm, symmetrical bayonet) and not a BAU15S (offset). Choose the appropriate lighting color: white for reverse lights, amber for turn signals, red for brake lights. If your vehicle reports an error on the dashboard after switching to LED, choose a model with a built-in Canbus resistor, which simulates the consumption of the original halogen.
