Daytime running lights not working - 2002 Honda Accord

Head light have two relays.one for daytime and one for normal night. the daytime switching the light to serial circuit and if one bulb is out down both Leigh quit working. Inspect your light high and low beam for normal operation . Inspect your fuses . Swap the daytime relay with identical one.and under the dash is module for daytime running light. inspect the red/black wire for ground from light switch and light blue/ yellow for power from 15A ECU-B fuse
good luck

There is a microprocessor in the instrument cluster that grounds the DRL relay - do you know if the relay has power from the headlight fuses and is being grounded by the processor ?

The problem with HID lights is that they require 12 volts or more to work. Daytime running lights on require 6-9 volts from the module. So when the original lights are replaced, the daytime running lights will not supply enough voltage to the HID ballasts to turn them on. The result? No Daytime Running lights. Another alternative is to purchase LED strips and place them around your headlights with a fused accessory power from the ignition switch. When the car is on the strips light up and you have Daytime Running Lights!

you may have the wrong type of bulb. I believe the daytime light requires a dual element bulb did the plug go on ok?

Daytime runnning lights mean that the headlights are on in the daytime. On my 2005 MAlibu I can turn these of by truning the headlight swithc from auto to off.

If the relay does not help your modual has burnt out that is a common failure

the lights are controlled by a module, it is the DRL module, replace it. also try this
On the inside of the car next to the light switch there is your dome light button. GM made it to where you could turn off the daytime running lights by pushing it three times in and out. Turn the vehicle on then do this. Your daytime running lights should work after this.

perhaps i missed something here... lowbeams and daytime lights are about the same.... be that as it may... the merely obvious thing is that the low beams are burnt out.... next thing would be that the relay for the day time lights could be defective... it's often mounted on the firewall.

I had this issue with my 1999 C1500.  I had to jump my truck a couple of times, because I left the inside light on and I found when I did this my daytime running lights worked briefly.  I wondered why, but didn't give it much thought.  I had to replace my battery a couple of months ago and my daytime running lights started working all the time.  Even though my battery would start my vehicle, run the interior components, etc., it didn't have enough voltage for the daytime lights.  Check your battery voltage under a load, see if it helps.
