LED car turn signal features:
1. 144SMD 3014 LED lamp bead, small size and high brightness;
2. New material FPC circuit board, the circuit board is soft and bendable, and the circuit is integrated. [The lamp body has glass cover protection];
3. Non-polar wide voltage constant current source design: LED car turn signal can work in small car (DC12V-24);
4. In-situ design: plug and light without changing the circuit;
5. The aluminum parts are actively dissipated, and the heat dissipation effect is fast;
6. Less solder joints to improve product quality

if need install 4pcs at the same time, very few cars will cause error or hyper flash issue, please buy resistor together to solve the problem, 4pcs bulbs need 1pair 25W Resistors.

NOTE:
1.If the bulb has a hyper flash or an error, please add a load resistor decoder.
2.With DC 12v power supply, it can be judged whether the bulb itself is working.
3.Please confirm your socket before making an order. Thank you.
