I want my H7s to have a very bright white look (when you look straight at the front of the car. Right now I put in Xenon bulbs and they still show up with a yellow tint. My H7s are the inside lights (daytime running lights).

 

you have regular halogen bulbs eh, might want to try the mtec cosmo blue 4700k

 

the Mtec 4350k super whites are whiter than 4750k cosmos blue

 

I have the Mtec Cosmos Blue 4750K H7s for the dipped beam and HB4 for the fogs. Look awesome and in my opinion the best mod unless going with HIDs. Maybe not the whitest but possibly the best HID look halogen bulb around. Definetly gets rid of the yellow from stock halogens.

 

go HID. Got em on my low beam and fogs now... love it!

 

'cuz on pre-LCI in DRL mode the bulb is not using full power only probably 80% (probably for longevity) so in reduced power it'll not be white ... due to that you can't put HID for your DRL 'cuz the HID kit will not power up properly w/ reduced power.

Not to change the subject ... do you have pic of your ride? I like to see the Brembo rotor & the drop on the Performance Spring Set ... is it H&R spring?

 

I have gp thunder 8500k. It has nice blue hue, but feel it is a bit dim. Anyone tried both mtec and gp? Need your experience on both. THinking of changing my gp thunder H7.

 

Here's the Cosmos Blue:

They are available in standard 55W and 100W (I ran the 9006 100W in my fogs for ever without any issues)
