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!
#67 bulbs are still available http://www.dodgecharger.com/forum/index.php/topic,103754.0.html They are physically smaller, 1157's come too close to the lens and could melt it.
My car is stripped down for restoration right now but if you scroll down towards the bottom of the link, there’s a picture of a car with #67 installed. The volt difference of .3 isn’t noticeable.
My 66 Dart is the same way. You need factory bulb numbers or you need to do your homework and find the correct candlepower. I have lights in the trunk that could be changed to 1157's with a couple sockets and some wire. It would be safer to have 2 lights per side for brake and turn signal. It would look more balanced as well.
There is a 2057 bulb too that draws less current and runs cooler. Also there is a 2357 bulb that is brighter on the brake light element side,,,, Ed
This is one of my pet peeves. People also are installing 1156 in the two inboard spots. Too bright for running lamps
I picked up #89 bulbs at WalMart the other day. Physically smaller glass envelope, but you can't tell through the red lens. Correct brightness to match the other running lights. The other option would be similar to what the OP said and add 2 1157 sockets, but for me, if I did that...I'd wire in all the wires, and have six brake lights and six run lights. And at that point, I'd build some sort of a sequential setup just for kicks...
