Hi, new guy in town here.
Got my RDX back in May. Want to upgrade the DRL but not sure what is the best in the market.
Much appreciate for all the ideas and helps.

Wow, no one has any info for the DRL replacement with HID ?
The reason I asked because most of the threads that related to DRL or Fog lights are using LED. And LED in DRL does not perform well in high beam, which something I don't want to loose.
I did some searching on the web but wasn't sure because RDX parts are still "NOT recognized or Approved" by consumers like us.
So, any info out there is/are much appreciated, in advance.

DRL and high beam are on same bulb. When high beam is not turned on, only very small voltage goes through the circuit and produces a very dim light as DRL.

Being said, if you replace it with HID, it won't work. When you turn on high beam, it will work since then there is enough juice to light up the HID bulb.

DRL is 9005.

Thank you for the info samrdx15.

Is there anyway to modify the HID to work in conjunction with DRL ?
There is no instructions available on most of the HID seller websites.

Does anyone know if there is an LED bulb that can do both DRL and high beam?

^ I would also like to know.

I believe there was a thread on this a while back that said the answer was no. It really boils down to the fact that while the LED lights are bright for DRL's they suck when it comes to a high-beam situation. It might have been in the 4th gen TL forum I saw that - the headlight config is the same.

I have heard of LEDs used for both DRL and High Beams in the 4G TL section. I'd have to do some digging on the brand and model.

Most people run LED's because they don't need them as bright as their headlights but to also get rid of the dingy white. Not many run HIDs for DRL's.

You could run DRL and high beam with HID.
1. You will need to find out the voltage the car is sending to the DRL.
2. Wire up the HID kit with a relay switch that is designed to work with voltages between 12V and what you measured when the car runs the DRL.
3. Blind everyone that drives by as you are now running high beams in broad daylight.
