Features and Performance Details

• Each bulb has 16pcs high power 3030 Led chips for perfect beam pattern, high light output but low consumption
• Wide-range voltage and intelligent constant current IC driver to avoid digital and VHF radio signal interference
• Heat-resistant Aluminum circuit board for better transfer efficiency, solid alloy body for better heat dissipation and longer lifespan
• Dual function: Light up xenon white for parking lights or daytime running lights, light up amber for turn signal lights
• The turn signal flashes "amber-off-amber-off" instead of "amber-white-amber-white" much easier to see. ( Most switchback bulbs in the market flash amber-white-amber-white )
• No polarity design, and compatible for both standard and CK socket, comparable to OEM sized halogen bulbs and fit directly into multiple sockets such as 3157 3157A 3057 3155 3157NA 3357 3457 3457A 4057 4114 4157, etc

IMPORTANT NOTE

1. These will only work for dual function lights that have both the parking/city light and turn signal function in one bulb
2. The 50w 6ohm load resistor or flasher relay may be needed to prevent the hyper flash or the bulb does not blink for vehicles with built-in Canbus system
3. Pls confirm whether this bulb fits your car before purchasing
