So here's the situation. I've got LED brake lights installed and the car's computer is giving me brake light out warnings. So to get rid of the alerts, the only real solution is to install load resistors to simulate the load of a incandescent.
The brake light is basically a 1157 5W/21W dual filament bulb. I've figured out that I need two sets of load resistors per bulb, one for each filament because the computer looks at the current draw from both filaments.
I've got some generic 6ohm/50W wire wound resistors, which seem to take care of the 21W filament, but i'm trying to figure out what values I should pick to simulate the 5W filament. Could somebody help me figure out the resistor values which would be equivalent to both filaments? It should be calculated at 14 volts.
I don't know the exact current draw by the LED array, but it's safe to assume they're about 75mA/300mA respectively for each filaments.
Thanks!
PS : i've figured out I would need a 40ohm resistor for the 5W filament, correct me if i'm wrong... I'm still unsure of what wattage to get for it though.
