Default Headlight issues

Ive read, i believe on here, that our headlights wiring is bad as in it shorts, etc. My headlights work every once in a while and I replaced the push pull switch and it worked for about a day then back the same 50/50 chance for lights. I wanted to confirm what ive read about the wiring and if I could put a relay in there to help with the problem

Its not the wiring that is bad it is the design. The bad thing like you said is they should have added individual relays to power the headlights.

It would be easy to add in relays.

Finally, something to do lol. Now my question is, how many watts are the headlights if anyone knows (just a general idea) I have a 30amp relay and I know that can handle up to 360 watts (if im right) So Im thinking that should be plenty, just wanted to triple check lol

and this will sound stupid but i should hook it up on the power wire right? and leave the brights and what not alone, or should i do 2 relays? I think the headlights share a common wire, power i believe.

What is the name of the part used to hook a lot of "extra's" to you battery? Where it connects to the battery and then you can hook many things up to that part, so I dont have 1000 cords going to my battery. Thanks for the help crazy

i used a 4 gauge wire running to a 90 amp breaker then off of the breaker i have my individual ckts with their own fuses. one high relay one low relay. power is seperate for low and high beams. ground is common. add a new ground while your at it. also the lows are 45 wat each and high are 65 watts or less each. i used 20 amp replays on myne. the high relay on myne also drives my driving lights and i've no probs at all. just use the cab wires to signal the relays and your good.

As for hooking up wires to the battery I use these type of terminals. I love it expecailly it is a type of quick disconnect with no tools needed.

if you want to know amps just divide the number of volts into the number of watts. a single headlight is 55 watts, divide it by 12 volts and you get just roughly under 5 amps per headlight (closer to 4.5 amps). multiply by 2 (# of headlights) and you got the amps needed for a relay. a 30 amp relay is more than enough for both, i would look elsewhere for the problem.
