PROBLEM: ONE OR BOTH LED HEADLAMPS ARE FLICKERING EITHER CONSTANTLY OR INTERMITTENTLY
LED flickering or hyper-flashing is usually a sign of low input voltage. Unlike halogen headlamps which will simply dim with low input voltage, LEDs will flicker.
- Use a multi-meter to test the input voltage (the application’s output voltage). Anything lower than 10.5v could result in flickering.
- If only one side of the headlamp is flickering, swap the LED driver (the little black box) over to the other headlamp. If the problem still stays on the same headlamp, there is low input voltage problem caused by the vehicles circuit on that headlamp which will need investigating. If the problem shifts to the other headlamp, the LED driver may be defective, please lodge a Warranty Request.
COMMON CAUSES OF FLICKERING LED
The most common reason we encounter is the vehicles battery supply voltage is reduced. This could be a result of either dead cells, or due to the fact that the battery is getting to the end of its life cycle. We recommend you have your battery tested and replaced as required.
The second but more uncommon reason is that the vehicle headlight circuit is restriction supply volts. This will need to be investigated by a qualified auto-electrician.
Flickering can be the result of Jeep’s PWM circuitry, also known and as hyper-flashing. To alleviate this, please use our our H4 Error Decoder
