FAQs
These LED bulbs are rated for 30,000-plus hours of operation, significantly more than a standard halogen bulb.
Yes. These bulbs are rated for a 12V to 24V range.
This bulb pair carries a 6 month warranty.
This product is covered under an exchange-only policy.
It is sold as 1 pair.
No. These are plug-and-play bulbs that go directly into the standard P21/5W BAY15D socket.
No. This is a dual-filament P21/5W BAY15D bulb built specifically for combined brake-and-tail sockets, where the offset bayonet pins line up both the 21W brake filament and the 5W tail filament correctly. It is not designed for a single-filament socket.
As a general rule, a red bulb suits a red tail lamp lens so the emitted color matches the traditional look, while a white bulb suits a clear or smoked lens housing where the lens itself is not tinted. Choose based on the lens color on your vehicle.
No. These bulbs are built as CANBUS error-free and hyperflash-free, so they avoid the flickering and dashboard error codes that some LED upgrades trigger.
It is designed to be suitable for all Indian car models that use the P21/5W BAY15D socket in the brake and tail light position.
Yes. It is a dual-filament design, so a single bulb provides both the bright brake-light output and the dimmer tail-light glow depending on which filament is powered.
Also Sold As — Cross-Reference for This Fitment
Brake and tail positions are where dual-filament naming causes the most confusion. This bulb covers the following designations.
| P21/5W / BAY15d | 1157, 7528, 2057, 2357, 1034, 1154, 1016 |
| Base | Dual-contact bayonet, pins vertically offset |
Before you order: Dual filament, so it drives brake and tail from one bulb. A single-filament 1156 will physically fit but leaves the second function dead.
