i have a mazda 3 2004 s sedan does anyone know how to install fog lights? or does it have to be taken to a shop to be done?

 

Are you thinking of going aftermarket or OEM ?
The factory installation kit is not very hard.... just a little time consuming...
If you are interested in aftermarket lights... you could probably mount the lights in the factory location with a little modifying.

M34MYSON

 

OE kit shows retail of $250. Have not installed one yet but looks the connectors are already there behind the hole cover for lights. If you installed one M34MYSON where did they put the on/off switch? OE is on the headlight stalk.
