74 challenger I'm happy with these:

Rear replace1157 = https://www.amazon.com/gp/product/B01KLGRIR0/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
For the rear inner lenses on a 74 they are just reverse lights. I sprayed the clear lens vht nightshade red and wired it to the outside lamp so they work together. Way brighter now.

Front replace 1157 = https://www.amazon.com/gp/product/B07FBZVYQY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1, these are also way brighter.
