- Please try to reverse the polarity of the LED light if you found that the LED light is not working properly after installation
If you are using these LED light bulbs to replace the Turn Signal blinker light, Tail brake Stop light, Parking/Running light or the light on latest / European vehicles; depending on your vehicle electric circuit, you may need to add a pair of Load Resistor to prevent hyper/error flashing, error code message or malfunction problem
Since the size of this 380 P21/5W 1157 LED light bulb is slightly different with the stock/OEM bulb, so buyers must make sure this LED bulb is your vehicle's correct bulb type and can fit into the light housing of your vehicle before buying

What is COB?
COB (Chips on Board) is a new technology of LED packaging of LED light engine. Multi LED chips are packaged together as one light module. When it lights up, it looks like a lighting panel.
How COB LED light source works?
In COB lighting, single LED chips are placed directly on a circuit board (or substrate) which has thermal properties to disperse heat. Heat dissipation is a very important aspect of LED lighting since it can have a major impact on the life expectancy of the luminary. Therefore, COB lighting can have a higher LED chip density and achieve higher light level while maintaining or improving life expectancy.
Advantage of COB:
COB lights are a more efficient form of LED lighting for general or automotive lighting applications because:
- light has a more uniform appearance
- better life expectancy
- achieve higher light level over a large area
- COB is more stable and reliable than standard LED package
