You can buy stick on lens film,just don’t wet it like tint. Some tinted bulbs you can just buy.

So I bought a new converter but after measuring I don't think it will solve this problem. This particular 5.3 and 700r4 is tight making the converter almost bottom out. This trans on my beat to death 5.3 has more room. Never seen this nor do I know how to fix it.
