I am working on lighting. I replaced the overhead dome light with a 36 ultra bright LED panel. This provides a much brighter interior lighting and I like the cool blue light it casts. While not period correct for the car, it is a minor update I am willing to live with.

Don't mind the mess, I still have the dash out as I am taking my time to finish up all the work I can do while it is out. All the packing seen are parts waiting to be installed.

Next moving on to the biggest flaw I have found with the Meras. It seems most if not all shipped with incorrect tail light wiring as I have seen at least 6 examples. My theory is that the Mera went on sale in 87-88 and it was being planned in 86. Since it was going on V6 cars it is possible they originally designed the Mera around the fastback GT which has amber turns. However, most of the Meras were built on SE V6 cars or Formulas to save cost. The notchbacks have only red brake and turns. So when putting the lighting in the tail lights it seems they simply hooked the lights up exactly how they were wired which means that with parking lights on both amber and red lights are lit up and when applying brakes or turn signals both the amber and red light up as well.
Frustratingly this resulted in a lot of Meras having their wiring hacked up by unqualified people trying to fix this. I have heard many owners complain about the mess the previous owner left the tail light wiring.
Another issue is the tail light housings (not the lenses) melt over time from the heat of the light bulbs. To counteract this I have changed over to all LED tail lights. I also fixed the wiring so the ambers only come on with turn or hazards and the reds are brake and parking lights. Anyone in the future working to correct this, follow your tail light wiring harness up to where it plugs in near the battery. Once there look for the single white wire that loops back into itself. Cut that wire and it will separate the brake signal from the turn signal. It is that simple.
Pictured here after many hours is my correctly working lights.
