Compared to the LED bulbs I had in my fogs its a night and day difference. Can't say in regards to OEM halogen fog light bulbs because when I purchased my car one of the bulbs was burnt out. HID foggs really made a huge difference in my case though, can't believe I waited so long!

 

@Alphaman19 - They put out a lot of light, and may disrupt other drivings. I would not recommend doing this if you plan on driving with your fogs on all the time.

Throws a lot more light onto the ground

 

looks really good what kit and wat did u go with? I havent got my gs300 yet people keep waisting my time.. Where do you mount your ballast at? zip ties? lol

 

@nelson09 - Thanks. that pic helps
Question: Are you high beams on also?

 

No sweat, glad to help fellas.
I mounted my ballasts up on top of the front bumper impact bar using both 3m double sided tape and then zip ties around the ballast and entire bar.
I went with the 35 watt 6k kit from ddm tuning, I'll probably end up going back to a 5000k lows and pick up another kit for the foggs in 5000k also...nothing wrong with 6000k but i prefer the look of the 5000k bulbs i had in my lows before.
no high beams on that's just lows and fogs
