Loose ground connection or more than likely an alternator that is barely working . Have the alternator checked at any Auto Parts Store or check it yourself. Connect a multimeter set to the 20 volt DC scale to the battery with the engine running at idle. You should read from 13.5 to 15.5 volts. Any less and the alternator is failing and needs replacing. Also make sure the alternator drive belt is not slipping.
This is an illegal modification.
A common reason for dim headlights are failing bulbs that need to be replaced or improper cleaning. It may also be a more serious wiring issue that will need additional work.
The most common cause for dim headlights is a bad ground connection. Headlights draw a relatively large amount of current. Any loose or corroded connection in the circuit will drop a large amount of voltage, which doesn't leave enough for the headlights to operate properly.
i have a 98 blazer and read in the manual that you have to use the dome override button for this Dome override button has nothing to do with headlights,but with the interior lights in your vehicle. So it depends on what your problem is exactly.
There dim because the Plastic lens is faded or yellowed. You can clean the headlight. -------------------------- A place called partstrain.com might have them. I have bought a couple things from them and they are pretty good. Maybe they have yours. VBd If the headlight lenses are yellowed or fogged over I know how to fix that. Get a product called Crystalenz. I used this stuff on a Dodge Caravan and it cleaned them up like brand new. It was really easy and only took 15 minutes on each light. Check out www.crystalenz.com
i have a 93 firebird and my relays right next to my headlights under the hood so maybe its there
the speed you are travelling in a vehicle is faster than your headlights are allowing you to see in front of you. If your headlights were very dim and you could only see a very short distance ahead it would be very easy to overdrive your lights. Or like running as fast as you can, in the pitch dark, in a place you've never been before, with a flash light that is so dim you can barely see 12 inches ahead
No, The earth does not have stars. Stars are like the sun. They are so far away that they do not look bright to us. Look at car headlights. When a car is far away, its headlights seem dim. They get brighter as the car gets closer.
Illumination is the ability to lighten the screen or darken the screen with the other dash lights on the vehicle. normally you will have two orange wires coming from the cars wiring harness one with a white stripe one without. The orange/white wire will make the stereo dim or brighten with the dash lights. the solid orange wire will dim/brighten the stereo with the headlights. so if it is night you will have the headlights on, when you turn the headlights on the stereo dims so the light from the stereo will not blind you at night. while the headlights are off the stereo will be bright so the stereo light will be visible in the daytime
Check the grounds on headlights
They were encouraged to have their shirt tails hanging out in ww2 so that pssing cars with dim headlights could see them and not crash into them.
If its a full Size Blazer, call local junk yards, may be able to use a 350, if so there are a number of them around.
