Automotive LED replacement bulbs promising brighter, whiter rear and signalling lights. Drivers who want clearer reverse, DRL and brake illumination will welcome the crisp 6500K output from OBOLED P21W 1156 LED Bulbs. Are these an easy, reliable upgrade for most cars?
⚡ At a Glance
- • Light Output: 36SMD 7020 LED chips, 1000LM per bulb at 6500K for strong white illumination
- • Best for: Drivers who want brighter reverse, DRL, brake and turn-signal lighting
- • Not ideal for: Vehicles with uncertain bulb size or sensitive electronics without load resistor
36SMD high-power 7020 LEDs deliver 1000 lumens per bulb. Built-in intelligent IC driver and aviation aluminium aid stable current and heat dissipation for long life.
Brighter, clearer rear illumination – With 36SMD 7020 high-power LED chips
An array of 36 SMD 7020 LED chips produces a combined luminous flux of 1000LM per bulb at a 6500K colour temperature, running from 12V to 24V and consuming about 5W each. Built-in intelligent IC driver ensures stable input current for consistent output.
Noticeably stronger white light improves visibility when reversing and signalling, making night-time manoeuvres easier to judge.
Longer service life – Thanks to intelligent IC driver and aviation aluminium construction
Intelligent IC driver regulates current to protect the circuit while aviation-grade aluminium improves heat dissipation, keeping LEDs within a secure temperature range. Rated life is up to 50,000 hours under normal operating conditions.
Reduced need for frequent replacement and steady brightness over time, so reliability improves across seasons.
Simple swap-in upgrade – With direct fit for common P21W/1156 BA15S sockets
Designed to fit codes P21W, 1156, 1156A, 382, 1003, 1141, 7506 and BA15S, enabling plug and play replacement for backup, turn-signal, rear fog, daytime running and brake lights. Some vehicles may require a 50W 6ohm load resistor to avoid hyper-flash or error codes.
Quick installation for most owners, but check original bulb code and vehicle manual and fit a load resistor where needed.

❓ Frequently Asked Questions
Q: Will these bulbs fit my car?
A: These bulbs are designed for P21W, 1156, 1156A, 382, 1003, 1141, 7506 and BA15S sockets. Check the vehicle owner's manual or original bulb to confirm the correct bulb code before fitting.
Q: Do they work on different vehicle voltages?
A: Operating voltage is 12V to 24V, so suitability covers most passenger cars and commercial vehicles that use those voltages.
Q: Will I get hyper-flash or error codes?
A: Some vehicles may require a 50W 6ohm load resistor to prevent hyper-flash or trigger error codes, so fit a resistor if the vehicle shows rapid flashing or dashboard warnings.
🏆 Our Verdict
Suitable for drivers who want a simple upgrade to brighter, whiter reverse and signalling lights. Built-in intelligent IC driver, aviation aluminium and a 36SMD 7020 LED array deliver 1000LM at 6500K and up to 50,000 hours of life. While initial cost varies by retailer, long lifespan and reduced replacements offer solid long-term value.
