Chrysler Jeep - Defective OEM Rear Bulbs

I thought I'd post my dissatisfaction with Chrysler Jeep. This is the second rear light bulb that's burned out on my $42K Jeep. The driver side rear bulb burned out around 5K miles.. now the passenger side rear bulb burned out at 10K miles.

What do I need - a 100,000 mile bulb warranty?

One would think Jeep could get their act together.... defective bulb filaments. I can't believe Jeep can't manufacture a bulb that lasts longer than 10K miles. They make spark plugs that last 100K miles. Old fire house light bulbs will burn for 100 years.

Btw... this is my only complaint, so far.

It sounds more like you have a voltage problem. Check it.
Maybe your alternator is stuck in cold weather mode and is cranking out higher than normal voltage.

Stay away from the LED drop-in replacements. They don't work properly and aren't quite legal.

Hmmm. I just chauked it up to bad Chinese bulbs. Its just the rear blinkers that's burned out.

One would think the entire fillament would dissolve if there was a voltage issue.

My Cherokee has had the same bulbs for 23 years....

I guess I'll just replace it and if the rear blinkers only last 10K miles then I'll assume there's more than meets the eye.

The directional and brake light are on one filament and the tail light is on a separate filament within the same bulb if that's what you mean. Probably an issue with the "brighter" filaments for lack of a better term. Hilldweller would be more technical.

Actually this thread is more about complaining about nothing, than it is about complaining about defective light bulbs.

I said I was happy... how can someone be happy when they're complaining?

I'm a supporting member... I have a right to complain about stupid things. Stupid is as stupid does. Ante up and become a supporting member and you can be stupid too.

So... I guess everyone else is so busy having problems with defective heads, sand-laden cooling systems, leaking tops, etc. that they just haven't noticed all of their bulbs are burnt out.:)

At 60,000 miles, all of my bulbs are still working but I'm really upset that my original tires' tread is almost down to the wear bars. :rant:

^^^ That's all I've got. Everything is still working perfectly as it has from the day I picked it up.

It's some sort of bot or spammer trying to up their post count.

So... Hilldweller, now that I think back I may be the same side.. the replacement OE bulb that burned out. I'll replace it again, but perhaps I'll swap it out with a Philips long life this time. See if that makes a difference.

The double "L" bulbs are dimmer; that's how they last longer.
Before you drop in the bulb, use a multimeter on the circuit. Running and off with the lights on, blinkers on, brake lights. Check voltage and compare to what you have at the battery during the same running conditions. Also check for signs of water intrusion ---- look for a short to ground also with a continuity check. Last, check resistance.

Everybody has it wrong. U need high performance blinker fluid. That's why they're burning out. The old blinker fluid will not mix with the high performance stuff soo u need to flush all the old stuff out and start fresh. But make sure u jack the rear of the jeep up to a 45 degree angle to get rid of any air in the system.( u don't want really slow blinkers.)

Yep my blinkers skip a beat or two every once and awhile. Must be something in the control module

Very true. I use royal purple synthetic blinker fluid. Makes the blink way more smoother and faster...blinks last longer also :)

It sounds like a simple bulb problem but why not think outside the box. Maybe it's a shock problem. Maybe your shocks are defective and jarring the filaments, or maybe a combination of the two. Why not do what I did. Why not get some King shocks. My bulbs are still going strong after 23,000 :)

If that doesn't solve the problem so what. The ride and handling will be so vastly improved you won't care if you have blown bulbs or not...
