my turn signals are 7440 so what polarg M number do i get to replace them?

 

M12 for 01 TLs...

 

what color do those produce? bright white or bluish-white?

 

BRIGHT white with a SLIGHT blue tint.

 

that M # is for the front right? what is the M # for the rear turn signals?

 

I thought it was M-14 for the front turn signals?

 

Polarg M1 = Super Amber
Polarg M2 = Super White
Polarg M15 = Super Blue

Polarg M12 (Super White) replaces the "1157" twist-in bulbs in the front turn signals of 99-00 TL's.
Polarg M11 = Super Amber.

Polarg also has new (1157 type) bulbs that have a blueish-gold color but blink red, amber, white or blue when used as a turn signal. They are called G32's.
