H9/65W will give you 2100 Lumens vs 1400 for H11/55W. I know this is being done on other cars with no problems for the fogs. You can slightly alter the plug by shaving off a small plastic tab in the H9 plug. You can also get this for around $30...an adaptor..no mods required:



Has anyone here done this? NO, this isn't HID, so please don't *go there* and waste my time.

 

Decided to go another route H7 65W Larger 100% Xenon bulb 6000K. Used heavy duty harness:

65 watts
- 15% brighter than a standard halogen bulb of same color
- produces less heat than halogen 65w bulb
- filaments last longer than halogen 65w bulb
- available in 3350k yellow or 6000k cool white for most applications


Here are results of second option above:



Chevy Tahoe with HID Fogs 5000K to compare:

 

Bump due to added pics.

 

these just go in like the stock bulbs with those adapters on them? Any stock bulb versus the new bulb pictures?

 

those are real xenon bulbs i see

 

Those just plug in..they are stock size H11, but 65W with modified bulb and beefier filament.
That's not an adapter..it's a heavy duty wiring harness..just plugs in between bulb and factory harness! BTW, that does NOT come with those bulbs! Only with 80W bulbs. I ordered it separately from another place, but you could prolly get it from them.
Trust me...you don't need to see a pick of stock fogs here...just compare with the HID Fogs I have added to compare.

 

i used the h9 bulbs in mine and there verybright. well worth putting in

 

Having fog lights that are brighter than your headlights seems completely pointless to me. If you drive with these things on at night all the time and you happen to have to drive out into the country you'll be killing your night vision.
