Do I need a heavy duty headlight wiring harness

4 posts in this topic

I'd like to change my headlights to 85 watt EVO Lighting H13 bulbs. Will I need to put in a heavier duty headlight wiring harness on my 2013 Spark LS or will the factory harness handle it?

Hi Larry, why h13, I mean standard fitting is H4. Are these physical compatible? I mean can you put h13 bulb in H4 socket?

Anyway, coming back to your point of wire. Although each manufacturer keep some design margin so upgrading to 85 from 60/55w H4 should not be a issue, this is what I got reply from many people when I was working out for fog lamp (mine projector low beam 60w, factory std 35w). I prefer to lay higher thickness wire to avoid any heating due to additional load I am putting. And better you go with automotive grade wire, these have thin insulation and high heat resistance.

ChevyBeat, my owners manual calls for H13 bulbs.

Larry, pardon, as major vehicle I have seen are using H4 as headlight bulb, even bikes. So I was in that impression.

 

Have you decided to upscale wiring harness?
