I bought a 2015 Chrysler 200 and it came with led head lights but the light on dash randomly comes on saying its out i get out to look and it is but i shut car off and start goes away for a bit and comes back i changed one to silver star no problem with that one why wo
uld this be

Welcome to the forum. Was the car factory equipped with LED or are they lamps that a previous owner installed?
For best results, always use the type of lamps (OEM) that the car was equipped with.
The BCM is 'smart' power management and may be shutting off current to the lamps for protection. Fault codes may be stored in the BCM as to the reason why.

The LED headlights do not draw enough current (AMPS) and the TIPM believes the headlight bulb is burned out and then shuts down the power to that headlight... You can add a load resistor across each headlight wiring to fool the TIPM into thinking there are standard incandescent (filament) lamps there... I used 4 ohm 100w resistors and mounted them to the radiator shroud... You will be dissipating around 50watts per bulb and the resistors will get hot... The metal shroud allows the resistors to rid themselves of most of the heat... I wish there was a way to reprogram the TIPM to ignore the headlight conditions and leave them alone but programmed "smart" electronics in newer cars causes these problems...

Any idea how much wattage the computer is looking for?

The stock Halogens are 55 watts each.

I ordered a set of LEDs that draw 30 watts each and the headlights shut off after a couple minutes.

If I put in 50 Watt LEDs would that be close enough for the computer to ignore?

I believe that the BCM is only looking at current draw. No draw will set an open circuit (under-current) fault and excessive draw will set a short-to-ground (over-current) fault. Voltage will be high in an open condition and low in a short condition. I don't know how much lee-way the protection software gives you.

Welcome to the forum. You may need to install parallel resistors on the left & right headlamp wiring to 'mimic' the load of a halogen lamp. An example:

Most motorists connect LED lamps to the car's electrical network through a single current-limiting element - a resistor. Therefore, increasing the voltage on the battery leads to an increase in current through the LEDs. The LED, in turn, is a non-linear element and even a small voltage jump leads to a significant increase in current through the crystal. From overheating, an unstable region appears, which does not pass current constantly, but at regular intervals. This is the main reason for such malfunctions. The simplest and most obvious solution is to replace the broken indicator with more modern and reliable smart light bulbs.

Welcome to the forum. Actually they want more current draw, not to limit it. The circuit needs to mimic a halogen lamp load, or faults get set in the control module and the lamp flickers or shuts off.
LED current draw is a bit smaller than conventional bulbs.
The resistors are placed in parallel to provide another path and to increase load.
A current-limiter would be in series to add resistance to the path.

These are past discussions on LED headlamps:
Unless lamps are DOT-approved/certified/compliant & meet FMVSS 108, they may not be street-legal.

The BCM looks for a range of current draw for both the Halogen & HID headlamps. If the current draw is over or under the limits, the circuit can be disabled & a fault code stored in the BCM. Headlamps can blink, flicker or shut-off.
You will likely have to add a pair of parallel resistors to fool the BCM, at least. Currently AFAIK, there is no legal aftermarket solution for 'public highway use' LED conversions:

A lot of what I read on the internet is confusing/conflicting about this, much of it seems to be sponsored by or written by LED headlamp marketers. Check your federal, state (DMV) & local motor vehicle lighting laws.
