Well I got into it with a cop once before it costed me to, but to make a long story short, the front markers HAVE to be EITHER "amber or clear" no other color UNLESS you are a cop, firefighter, snow removal, etc, etc........only they have the right to have coloured bulbs, and in the rear red, clear, or amber and if you have a 94 mustang it should be red like my 94 built into the taillights :thumb1: good luck with the lighting issue just my 2 cents. :5:
