''The light from a headlamp is very dim. The electrical supply and earth connection have been checked and found to be in good other. State TWO other checks that should be made to determine the cause''

im stuck on this on lol any ideas? thanks

[projctnova]

id check the bulb...and id check the contact points. But suppose also checking that the lights are switchd on and not on side lights.

1. Fillament could be burning out?

2. Check internal resistance of the lamp, this could be due to incoprrect wattage of lamp??

..check some bonehead hasn't fitted a 24volt bulb..

The bulb Holder will have internal contact points in them. In older cars, these are Prone to failing.

Had this problem on my XR2. The Conacts inside the holder had corroded, so no amount of testing the supplies and changing bulbs would help.

Not enough information to answer the question.

By "The electrical supply and earth connection have been checked and found to be in good other" (assuming you mean "order" lol) does that mean the voltage is correct or just that the wires are good and unbroken? Or the contacts are Ok?

I would check:
1. Bulb condition
2. Bulb contacts
3. Wires are intact and not broken/damaged/shorted
4. Voltage on bulb contacts
5. Voltage on battery
6. Earths
7. Fuse and dim/dip relay

...so take your pick from those.

Although, if its a modern car, just plug it into a computer and see what that tells you lol

Wipe the headlight with a used tissue to restore clarity.

[brucer]

the reflective backing has faded.

[craig green]

Is it dim from the drivers seat or staring at it head on? LOL.

College must suck.

[MattBrown]

Reflectors inside broken?

24v lamp?

Relay dropping voltage?

Ask the examiners for a propper ****ing question?

Contactors gone?

Lamps inserted reverse?


Get a hid kit, or fit an xe?
