DRL Controller Daytime Car Running Light Controller LED 12V Dimmer Relay Control Switch Harness On/Off

Do what they say they will do...build quality lacking...but are cheap so cant complain can i.

Works, but blinking and stopping my indicator

Please don't buy this product it doesn't work. I connected mine and the lights stayed on all the time even after car was locked and left it for a while. I ended up connecting the drls to the ignition switch wire and works great.

There are absolutely no instructions apart from a very uninformative wiring diagram on the module, so you will need to have some experience with wiring to get your head around it. Hopefully this bit of info will help. To get the controller to operate DRLs in basic mode, you just need to connect the black and red wires to the battery, the white wire to a headlight dipped beam or sidelight feed wire and the blue wire to a feed that is only live when the ignition is turned on (this is the trigger to tell the module that the DRLs can be turned on) The green wire is also a trigger wire but I have no idea what it's actually for because when I connected it up it just caused the DRLs to flash on and off at quite a fast rate. I haven't connected the yellow indicator trigger wires as the DRLs are far enough away from indicators for them to be a problem. However, if you do connect them up, you will need to connect them to the indicator feed before the flasher relay. If you connect them to the wires close to the indicators, this will just cause the DRLs to flash on and off in time with the indicators. One point to note is that unlike many other DRL control modules, this one turns the DRLs on as soon as the ignition is turned into position 2 and doesn't wait for the engine to be started so that it can detects the higher operating voltage. I don't think this is too much of an issue as most DRLs are low powered LEDs and won't have any significant impact on the battery. When the ignition is turned off, the lights stay on for around 10 seconds as a guide me home feature, this is fixed and can't be adjusted or turned off. For the money, I think it's a well made item, I can't say if it is going to last as it's too early to know. I just wish that they would have made more of an effort with regards to the installation guide.

When this mharness was first fitted everytihg worked, DRLs dimmed when headlights turned on, but 2 months later they randomly switch on then off, turn on then off, blink, fade, you name it they do it. Cheap and not worth it.

Need to google this as it has a sticker with wiring hookup and also has a different wiring hookup embossed. which to follow?

When wired as per instructions, the DRL’s flash when wired up, when using dip, side and main beam. No fix for this and drl’s stay on now when it’s nighttime with relevant wires not connected….. is that even legal, I don’t know 🤷🏻

Got this because of its voltage rating. But more difficult to set up as powered directly from a power supply when ignition is on, which ment more faffing about. Others power up direct from the battery and DRLs light up when engine starts running as the alternator sends 13+ volts to the battery
