DRL Fix: Own a Honda Accord from 2016 or 2017 with the OEM LED daytime running light?
Chances are, it has burned out like many others and requires repair.
Previously, your only real option was to purchase a brand new headlight for over $300, and even then, the same failure would occur after some time.
The Problem: The issue with the OEM LED DRL is that it is powered by two LED chips.
One is near the side-marker, and the other is towards the middle of the headlight.
The central LED is over-powered by the LED driver unit inside the headlight, which causes it to overheat and eventually fail.
The Solution: Replacing the LED circuit board with a new one is necessary, but recreating the exact same part won't be effective, at least reliably.
These replacements utilize more LEDs than the original part so that the power from the LED driver is distributed among more chips, creating the same amount of light while maintaining a much lower and more reliable operating temperature.
But wait: Sometimes when the OEM LED burns out, it melts the end of the acrylic light pipe that acts as the DRL.
Then what?
Simple: slice 1/4" off the end with a dremel tool, use plastic polish to regain clarity at the end, and the problem is resolved.
Not all Accord lights with dead LED DRLs have burned the tip of the light pipe, so in many cases, there's nothing more to do than replace the LED panel itself.
OEM+: This is an OEM quality part, engineered to avoid the failure.
They utilize eight Philips Lumileds Z-ES LED chips that match the white color of the original DRL in case you're only replacing one and are built on copper boards for maximum heat conductivity.
Plug n Play: They are a direct replacement for the original part and will plug directly into the sub-harness inside the headlight.
One connector and two screws are all that is needed for replacement.
AFTER YOU ARE IN THE HEADLIGHT.
YES, YOU HAVE TO TAKE YOUR HEADLIGHT COMPLETELY APART TO REPAIR IT; THERE IS NO WAY AROUND THAT.
Why?
Hasn't Honda recalled these headlights for this issue?
It's extremely common!
