I used a 50W 12 volt landscape bulb and a minature relay to simulate overall incandescent bulb impedance.

Suggestion
However, I would like to replace the third brake light with the LED version (both places, including the wing) but I worry this might be too little of a load.

Suggestion
You just need a 6 or 8ohm resistor wired in parallel for each brake light you replace with LED.

Everything is fine now except I can't use my LED lights.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Just a heads up. I installed the LEDs and they were to die for. However, as most of you know LEDs draw less current than than OEM lights. Conclusion, I had to reinstall my OEMs because the LEDs caused the ABS and PSM to malfunction and throw warnig lights as they are all on the same circuit. Everything is fine now except I can't use my LED lights.
I had the same problem on my '99 - it was exacerbated by my underdrive pulley. For some reason, the LEDs plus turning the alternator more slowly made the issue much more pronounced - I'd get the warning lights once every couple of days. Since returning to a stock pulley, I only see the ABS/PSM issue one every 6-8 weeks.
You know all you have to do is install a load resister to correct this issue right?j If you decide not to go that route, please sell them to me so I can do it.
^ Even with resistor packs, the LED tails cause trouble for some folks. I'm stoked that I got my issue (mostly) ironed out - I think the LED taillights update the 996 nicely.
If the impedance matching of the circuit is done correctly, how could it still cause trouble? I agree the LED light update the backend very very nicely.
Does Delray Customs also sell the narrow body LED taillights? I have had zero problems with their widebody LED taillights. Agree completely on the updated look. I can't imagine going back to stock now.
I have the tails in my '02 C2, and they have worked fine for a year now with zero issues. However, I would like to replace the third brake light with the LED version (both places, including the wing) but I worry this might be too little of a load. Anyone done so successfully?
It's very simple. Each side brake light is 21w. The middle brake light has 7 bulbs 3w each so again 21w total.
You just need a 6 or 8ohm resistor wired in parallel for each brake light you replace with LED.
Incandescent filaments have an INRUSH of high current flow upon initial application of voltage, low filament resistance when cold.
I used a 50W 12 volt landscape bulb and a minature relay to simulate overall incandescent bulb impedance.
Relay armature coil is connected to brake light circuit and ground, bulb is "powered" with NC, Normally Closed, relay contacts. Bulb low filament resistance simulates brake light off impedance (enables CC), bulb is in circuit for a short period upon brake application simulating high inrush current.
The Third Light I purchased from Del Rey Customs has resistors built in.
I'm running C4S wide body rear LED tail lights, LED front marker lights, third brake LED with no error codes problems.
Buy a quality light with resistors built in.
