What makes dome lights come on when doors open?
The door switches as well as the dimmer switch each provide a ground to the lights when activated (dimmer) or opened (doors switches). 12 v comes from the crtsy fuse to all the dome and courtesy lights, so if they work with the dimmer switch, your fuse as well as your dimmer switch is good.
Why are the lights dim in my Hotrod?
If you have too big of a draw at the fuse panel already, you won’t have full voltage and you’re gonna have dim lights. Only a 2 volt drop in a 12 volt system is a 17% loss in voltage to the headlights. That’s why so many people have trouble with dim headlights.
Why do so many people have trouble with dim headlights?
That’s why so many people have trouble with dim headlights. The easy way is to use relays. Basically, what you are doing with relays is supplying a short cut for the power. Instead of the power having to go through all kinds of connections, switches, tons of wire, etc., you create a short path for it to go, free of all that other stuff.
Do you need to wire up lights in your Hotrod?
All modern cars have them. That’s because ignition systems are more powerful, headlights need more power, etc. Relays are simple to wire into the front harness. (See the lighting diagram below.)
How can I get my dome light to turn on?
Step 1. Inspect the dome light switch in front of the dome light fixture. Most dome lights have three settings: “Off,” “On” and “Door.”. If the “Door” option is selected, the dome light will turn on only when the door is opened. Flip the switch to “Door,” and then open the door to test the dome light.
Where are the fuses for the dome lights?
One fuse may specifically power the dome light, or it may power all of the interior lights, such as the map lights and console lights. Remove the fuse panel cover from the location where the specific fuse is stored.
Why does the dome light on my Kia not work?
The dome light works in the “on” position, but does not work when any of the doors are opened. The diode itself is about half the size of a dime which you can buy from a kia dealer for less then $20. You don’t have to disconnect the battery to do this. 1.
