Default Intermittent lamp out warning light

I've got a 2003 Dodge Ram 1500 with an intermittent lamp out warning light... it's very annoying because it will ding on and off 6 or 8 times in a row... then I may not hear it again for 5-minutes, a week, or a month, then it's back again. I'm guessing I have a short somewhere, but am wondering if there's a way to find out which lamp the computer thinks is out, so I at least can figure out which wires to start looking at?

I have a cheap Harbor Freight OBDII reader, but it either doesn't have the ability to gather this level of detail, or I don't know how to make it gather it!

Thanks in advance!

It is usually the tail light circuit board assembly that is going bad which is common. They are cheap to replace but no way of knowing which one it is. Also could be a bulb going out.

Thanks for the tips - bummer that the computer won't pass along all the information!

I had that issue with a headlight bulb. If it is a bulb it will eventually fail completely.

Then you will know.

I had/am still having issues with this. I replaced the circuit boards/all bulbs, headlight bulbs and such. The damn chime/lamp out light only comes on during bumpy conditions, or sometimes just because. We can go days without it, and sometimes we can't go 1 minute without it constantly chiming. Aside from the random times it may come on, most of the time it's during braking and left turn signal activation. I am lost right now.

2006+tipm controlled Rams do, but beware what you ask for. The tipm module shuts off circuits in faults after 256X's reading that error and there's no way of "turning ON" that circuit again. Only way is to pay $6-800 for a new tipm and requires dealer programming. So, beware what you wish for...lol

I'd say circuit boards as well.

03WhiteRam, have you replaced the license plate bulbs along with the 3rd brakelight bulbs? If any of those bulbs are bad, it'll set off that dinger as well.

Now that I think of it, the left liscense plate bulb has been giving me issues with flickering. I just spoke to my wife back home and she is saying it still chimes when she uses the left turn signal and braking. I don't know what else it could be. I guess I will clean all the connections and recheck.

I'm a computer guy, so it's just annoying to me that the computer trips a dashboard indicator and dings a bell, but for whatever reason, it's not important enough to log an error code that I can read via ODBII or any other way (like using the odometer as a display) that could tell me exactly which bulb the computer "knows" (thinks) is bad.

Everything you just said about tipm (whatever that is!) also is just crazy in this day and age. Let me stick an SD card in the glovebox and log everything!

Okay, I'll take my nerd hat off now.

03Whiteram-If it is coming on during braking and left turning it means it is one of the turn bulbs. I know you said you replaced them, but it could be that the contacts are worn in the socket itself. I had this happen on a old Mazda B2300. Granted it did not have the circut board but the principle remains the same (don't know if circut board replacement replaces the socket themselves though.)

That is something I have yet to get through. I will be looking closer into the connector that locks into the circuit board. That's the only thing I haven't done yet, aside from replacing the connector on the liscense plate light, which I know has a loose wire.

Will be looking at the third brake light when I get home...that's the only thing I haven't looked at.

Mine did the same thing this past week. Step on the brakes and ding, ding. Lamp out warning flickered at first then stayed on, then would go out. Turns out it was the metal contact on the passenger side brake light bulb itself. There was a little bit of corrosion on it causing the intermitent warning light and the annoying ding sound. Replaced all four signal/ tail/ brake lights as the others looked like they would be going soon too. Cheap easy fix. '04 1500 Hemi. Check the bulb contacts. The filaments may look o.k. making you scratch your head thinking you have bigger problems with the sockets and wiring, when its just something small and simple. Yet hard to spot at first.

03Whiteram-You get your issue fixed yet? Definately look at getting the socket connectors looked at/replaced...

I should be back in the states in about 15 days.

Just a recap of what I tried in May while on R&R.

1. Replaced all brake/turn signal bulbs (4 each)
2. Replaced both circuit boards with new ones.

I have not:

1. Replaced the third brake light bulbs (don't know if this affects the left turn signal lamp out)
2. Checked/cleaned the connector to the circuit boards.
3. Fixed the shorted wire to my liscense plate lights (one flickers; don't know if it plays a role in the lamp out during braking and left turn signal)


This weekend, my wife took it up for the safety inspection and passed, eventhough the lamp out chime was dinging the whole time.

Will be digging into it when I get home. Can't wait to get out of this damned place.

Glad to know I'm not the only one loosing my mind. Mine does it on long trips, with or without the trailer in tow, day or night. I've traveled 14 hours and nothing, then it will just ding for a couple hours. Almost feel like buying a couple circuit boards so I can do a roadside swap if necc, have a long trip in August. I think I'll start with cleaning all the contacts and regreasing them w/ dielectric grease.

Have an 03 Dodge Ram 1500, my lamp out keep flashing off and on. Than the chiming noise does the same when the lamp out. Start acting up and than sometimes the chime noise start before the lamp out goes in and out.
