Earlier today I noticed that the L turn signal in our 2007 Dodge Grand Caravan was blinking at about 2x its regular frequency.
I figured a bulb was out, and indicated my L turns with hand signals for the rest of the trip.
Checked when I got home, and found the L rear turn signal not working. Pulled the taillight assembly (thanks, Mopar engineers, easy as any I've ever done) and removed the bulb, a 3057.
The 3057 had two filaments, one for the turn signal/hazard light/brake light, and the other for the running light.
I keep a stash of bulbs, but didn't have a 3057 on hand. Had a pack of two 7443 bulbs though, which looked similar functionally (two filaments, somewhat similar base) though smaller and less robust-looking.
I installed a 7443, and it seems to work fine - turn signals, hazards, brake lights, and running lights all appear to be the same intensity as the other side.
I didn't find anything online to say these bulbs are equivalent in function. I'll see how long it lasts.
