Alright so as the title suggest I'm looking to for a pair of LED H4 fog lights. (Before I get warned about the uselessness of the LED's I am aware and I can't remember the last time I needed to use the fog light or the high beams, 99% of the roads near me are lit up) so basically I'm trying to get the whitest bulb I can get to match the low beam.

The reason I'm looking for LED is because one, they are white (Unlike the broad spectrum incandescent lights) and two they are less likely to burn out (I do a lot of short range driving and the fog lights auto turn on/off)

So anyone have any suggestions for any LED H4 bulb that DOESN'T create hotspots within the reflective housing?

 

so u plan on having the foglights and low beams on at the same time?

 

I'm in Canada so we got DRL'S plus I drive with the lights on auto so the foglights pretty much turn on/off with the car (Except like you said when low beams are activated). So mostly I want to get rid of the ugly stock light during the day, as far as Low+fog I would have to see how it looks.

 

What year is your car? and is it Coupe or Sedan? i have an 06 G35X and have the same issue. the daytime running lights are not cool.

 

I have an '05 coupe, I went for the Mtec 2x 4350K, which are decent but still yellow.

 

One warning when trying to use an LED bulb in a factory DRL: what we see as "low-voltage" dimming of the halogen bulb is usually a pulsated 12v. Since the filament takes time to warm up and cool down, we end up with a dimmed bulb. LEDs have a much quicker start and stop time, so what you would end up with is a flickering bulb that appears rather dim. A solution to this is to add a low-pass filter to smooth the flow.
