I had three problems and this is what I did.First of all light bulbs are not creative egual.I always tend to by a spare so I brought 3 yellow bulbs from one of my often used vendors {not there fault they got them from some one esle}this is a 67 coup front yellow turn signals and parking lights.After rechecking all the grounds I isntalled the bulbs and the driver side buld was much brighter than the left.So I remove and replace it with another new bulb and it was less bright.So now to the left side not as bright so I replaced it with the bright bulb from the right and you guess it both are now equal in briteness go figure that one out it work so onto the next one.The rear drivers side was briter and when I used my turn signals my center console would blink with the turn signals.Ground?Replace the bulb was a 1157 I had a 2057 replaced it with it and it began to work and no more console flashing.Passager side had worked but than stop so replace it with 2057 and now everything is working nomal!Dome light stayed on always door switches reajusted light still stay on.Started to remove dome light and the light went off.Reinstalled dome did not tighted completly problem solve.Screws did not seem too long must been a hair.Reartail light last problem found by luck.The new Tywone tag light brackets are junk but what you going to do the out rubber on mine 5 monts old is dry rot and came apart the tension that holds the spring on the bulb was lost.The spring is on the out side an rap in rubber.This is what I did Got and old ball point pin took the spring out remove the wire from the housing slide the spring on the wire slide the wire back through the housing install the bulb.Make sure the spring is not too long test fit the bulb first.Works for me and now I will not have to wait for a replacement.I hope this can help someone else down the rode thanks fellows for all the help 7 years all I need now is a wheel alignment and tags I can see the light.
