Hello Welcome!

Here is a list of Bulb sizes for our vehicles.

Fog Light (non LED Fog ligths)
  • H8 35w
Thanks!
So, after reviewing the entire thread and some other posts, I'm not finding much information on replacing stock FOG lights/bulbs with LED's. Is this a full replacement or just a bulb replacement? I see some of you have gone with yellow fogs and I see CollegeHills has what appears to be full replacements available.

Is there a bulb-only replacement? If so, what would be the best option?


thanks all!

The 2019 fogs and CTR fogs are led units. They will fit older Civics, but you'll have to splice the wires. There's a thread somewhere where someone did that.

You can also replace the halogen bulbs with H8 LED bulbs that are direct plug in replacements. Some of these have fans for cooling which tend to make noise and interfere with radio reception.

You say if installing led turn signals you need a load resistor? Where does that go? I’m replacing the side markers with smoke with led, do I need them? Or you mean the light in headlight housing?..

  • NOTE: When installing 2 sets of turn signals front and back, only 1 extra set of load resistors will be needed.

    Sorry my english is bad.

    Afaik you dont need resistor on side marker led. Resistor prevent the turn signal led to hyperflash but the one they selling(turn signal light) it has built in resistor.

    1 pair(front or back) turn signal led= no need resistor

    2 pair(front and back) you need 1 pair of resistor. You can install the resistor either in front or back.

    Someone selling a plug and play resistor on youtube.

I have a 2019 Sport Touring Hatch, I have LED's all round except the Fogs that are Halogen, so the H8 LED's are direct plug and play replacements? I've thought about changing them out for LED's ever since I got the car and I just stumbled onto this thread.
