The backlights on the insturment cluster of my 2003 Chrysler 300m keep going out on their own. It started over a year ago and was very intermitent (once every few months for just a few minutes) but lately has been almost every trip almost the whole time. Last night they came on when the car started and then almost immediately began flashing several times until going out and never coming back on.

An instrument cluster is the collection of gauges, dials and lights right above the steering wheel that tell you what's going on in your vehicle.
Generally, your car's instrument cluster will last the lifetime of the car and you'll never have a problem with any of them. However, when one of them fail, you'll have a problem that ranges from mildly annoying (the engine lights up and doesn't turn off) to inconvenient (the gas gauge doesn't register) to dangerous (the oil indicator doesn't work). Some of the more common failures include:
Erratic or non-functional gauges & inaccurate readings.
LCD not Stuck or fluttering needles on gauges
Burned out indicator lights
Burned out/dark spot backlighting
Loss of LCD display or erratic operation (number 8 showing as 0
You can replace the instrument cluster bulb with a regular halogen bulb, or use T5 led bulbs that come in a variety of colors (white, blue, etc.) They are inexpensive and will last a lot longer than the regular halogen bulbs.
They had a recall on that. We have a 03 Chevy Silverado where the spedometer would either sit at zero or get stuck at the last speed. It sometimes takes a few starts to get it going. We did receive a recall notice for the instrument cluster to be replaced at no charge, but the clause was it had to be under 70k miles. We bought our truck at 72k and it is around 1k to replace so we just live with it. I dont get how the milage would have anything to do with it. Wish I could be of more help...its very frusterating.
Look above your brake pedal and you will see your brake switch up along your brake pedal arm. It will either be
between the brake arm and the firewall so when you brake it pushes the
switch in. Or it will be between the dash and the brake arm so when you
brake it pulls the switch out. Most likely this switch needs to be replaced
insturment clusters on these cars are known for going bad and blinking on and off. get the cluster fixed or get a used one. there is a company on ebay that will fix it for around $75.00, with a lifetime warrenty. just go to ebay and type in 93-94 lexus ls400 insturment cluster. There ad will come up and just follow the directions. Trust me this will fix the problem. It is also cheaper than buying another one that has no guarantee.
I had the same problem with my 2004 yukon. It seems all the gauges in the insturment cluster are known to go bad from 2003-2006 in GMC and Chevys. The deaerships are trying to sell you a new instrument cluster which is pretty costly if your warrenty is up. I repaired the circuit board on my insturment cluster myself and everything is working fine now. Since hearing abouth this problem I have started repairing the insturment cluster as a side business. If your vehicle is out of warrenty and your intersted shoot me an e-mail (firstname.lastname@example.org).
