2357 tail lite bulbs or 1157?

Re the question of LED's for the dash, I put them in my 65 Dart and they look great. A bit brighter than standard incandescent bulbs, with a cool blue glow that makes the cluster look modern at night. My reason was to avoid damaging my rebuilt cluster and because those bulbs are a pain to change in-place and LED's should last forever. Look up the number in your owner's manual (105?). I bought on ebay cheap.
