I did this to my 69 charger tailights a while back and just want to share it. 95% of the chargers I see on YouTube and in person seem to have mismatched / wrong bulbs. The two inboard taillights compared to outer 4, 1157's So I replaced the two inner light sockets with 1157 sockets and snipped off the brake light wire, and only wired in the running light wire. So the tailights are all evenly illuminated. Maybe there is a different fix for the unavailable bulbs problem now? But this is how I fixed it. I hope this helps someone? Have a great day!
