License Plate Light Bulb Problem
Posted by: Robert ()
Date: April 09, 2012 01:35PM

Sorry, but I posted this incorrectly the first time.

Again, I'm having a problem getting the license plate light bulb to work. I've changed the bulb; I've checked to see if there's a fuse associated with this light but I didn't see one. So, now I'm thinking it's an electrical problem. This sounds expensive. Don't want to spend a lot of money to fix this but the state of Virginia requires it to work to pass inspection. Does anyone know anything about this light?

Thanks,

Robert

It's probably the relay switch. These are probably $18.00 at Trak Auto. Labor will probably cost around $7,500.00 since it will require the complete disassembling of your car only to find out that it was probably a bad bulb.

Sometimes the holder that the bulb sits in becomes rusty and does not conduct the electricity correctly. If I were you, Id get a cheap test probe from an auto parts store and check the circuit.

Also, I guarantee it is on a fuse.

Relay sitch, huh. I didn't think of that. (By the way, the bulb has been changed numerous times only to get the same result.)

The lic. bulb wouldnt have its own relay. So unless there are other lights out, Id bet its the bulb holder.

Which fuse? The owner's manual doesn't even list it on the fuses.

How much does a bulb holder cost?

Use one of these ( a few bucks at the store) and see if you can get the test light to come on.

Turn on lights, attach the clip side to a grounded piece of metal or bolt and insert the probe into the backside of the bulb holder (where the wires meet the metal base that the bulb sits in)

If your car is older, the bulbs base is notorious for failing.

a few bucks for a new bulb holder. Mostly they are standard sizes. Cut and splice the new one in.

Fuse 7 --- 10 Amp License light & the left side turn, parking, marker and tail lamp


So if your left turn signal and parking lights work, its not a fuse or relay. Id bet a 6-pack your bulbs base is malfunctioning.

All lights work except License Plate. Sounds like the base is the problem. I appreciate your help and I'll let you know how it works out.

Thanks...Robert

I got a ticket for this once. Defective equipment, the fine was like $150 and my car insurance went up by $50 a month for 3 years afterward.

If you can't get it to work still after replacing the base, you could always run new wiring from your 12v switch back to the license plate lamp rather than try to dissect the wiring harness and see if there is a bad/pinched wire. Probably above your working knowledge though, any car stereo/alarm guy could do this for you easily.

One of my bulb bases is out, just need to use a multimeter on the socket and then the wire to the socket to see how far back the electricity comes. Should be a 7 dollar part unless it's an obscure part (for whatever reason the 09 tacoma's had their own model of license plate bulb socket) and then you may have to buy the kit (socket, bulb, window). Good luck!
