Automotive replacement bulbs engineered to boost visibility for signalling, parking and reverse lamps while matching halogen beam patterns. Drivers who value clearer, whiter light and straightforward swapping will appreciate the performance of Cenmoll P21W LED Bulb. Will the upgrade work smoothly with your vehicle electronics and fit like the original bulb?
⚡ At a Glance
- • Light Output: 3200LM per bulb, 6000K cool white, 360-degree full-angle beam
- • Best for: Drivers wanting brighter signalling, reverse and parking lights with halogen-style beam
- • Not ideal for: Highly sensitive vehicle ECUs that may need extra decoders or load resistors
High-power CSP chips and a 360-degree design aim to reproduce halogen beam patterns with far higher lumen output. Built-in intelligent IC driver increases compatibility while thermal management protects LEDs for extended use.
Clearer Night-Time Visibility - Thanks to 3200LM Bright Output
High-power CSP LED chips produce 3200 lumens per bulb at around 6000K, while the 360-degree full-angle design spreads light evenly to match halogen beam geometry.
Much brighter, whiter illumination improves visibility and makes signals easier to notice in poor conditions, helping other road users spot the vehicle sooner.
Straightforward Fit Across Most Vehicles - With BA15S/1156 Multi-Socket Compatibility
Compatibility covers many socket types including 382, BA15S, P21W, 1156 and several S25 variants, designed to match OEM bulb width for direct replacement.
Quick swap into turn signal, brake, tail, parking and reverse sockets reduces installation hassle and keeps lamps looking uniform.
Long Life and Stable Running - Thanks to Thermal Control IC and Aviation Aluminium Body
6063 aviation-grade aluminium construction and an intelligent temperature-control IC manage heat, while a protective PC lampshade shields LED chips and components.
Improved heat dissipation lengthens operating life to a rated 60,000 hours and reduces premature failure, cutting the need for frequent replacements.

❓ Frequently Asked Questions
Q: Will these bulbs fit my car's socket?
A: Compatibility covers BA15S/P21W/1156 and a long list of related sockets (see specifications). A user review notes the bulbs match OEM width and fit the original holes.
Q: Will they trigger dashboard errors or flicker?
A: A built-in intelligent IC driver is designed to work with 98% of vehicle computer systems; some sensitive models may need an additional CANBus decoder or load resistor, which the seller can supply if flicker or errors occur.
Q: How long do they last and is there support if they fail?
A: Thermal control and aluminium construction aim for a 60,000-hour lifespan, and every pair comes with a 30-day money-back guarantee plus a 24-month warranty for defects.
