EM wiring dangerous

[cobragene]

I finished my EM in 1999, headlights were always dim, fast forward just got to checking it, turns out all headlight power goes through the dash sw 14ga to the dimmer sw 16ga out one for both lo beams and the other for both hi beams 20 amp breaker No relays. Even more disturbing there was one 16ga ground wire for HL,marker lights, and horn. I put in a headlight enhancement system very simple similar to Patrick’s post and beefed up grounding . World of difference very bright, even the horn no longer sounds like a dog chocking on a bone. I am very lucky it didn’t burn to the ground, probably because I don’t do a lot of night driving. I started checking the rest of the system. No fuel pump relay, but it only draws 2amps on a 16 ga wire is that acceptable?
