Philips Standard Premium PY21W Car Bulb 12 V, 21 W, 2-pack
Genuine PY21W indicator bulb — supplied in pairs for replacing both sides at once.
The Philips Standard Premium PY21W is a conventional 12 V / 21 W signalling bulb with a PY21W base. Each pack holds 2 bulbs, enough to replace the left and right indicator together.
PY21W base for indicator positions
The PY21W designation covers both the bayonet base and the amber light colour required for turn indicators. Check the type in your owner's manual or on the bulb you remove.
12 V and 21 W for standard vehicle wiring
The bulb runs on the 12 V electrical system of cars, vans and motorcycles. Its 21 W draw matches the factory rating, so the lighting check system stays free of fault messages.
Two bulbs per pack for replacement in pairs
Both bulbs in the blister let you change left and right at the same time, keeping the two indicators equally bright. The spare also tops up the kit you keep in the boot.
