So I got a pair of LED bulbs for the rear license plate lights and this is what happened. When I have BOTH LED bulbs installed at the same time, the bulbs don't work and I get the warning signal at the dash. However, if I replace one of the LED bulbs with a regular one (meaning I have 1 LED and 1 normal on the car), both connect bulbs work perfectly. WTF? Works when I have one of each but won't work when I have both LED bulbs connected...

Here are the bulbs I got http://www.eautoworks.com/html/ORD-1-1-1-22502.cfm

 

You are underestimating the level of detail in the self test diagnostics on the Cayenne. The impedance of LED lighting is different from regular bulbs, 2 obviously puts it out of acceptable range.

 

LED use less power so the car thinks the regular bulbs are out....

 

how do they look ? besides the error

 

They look really nice...

So anyone has LEDs on the rear license plates?

 

I do. Red. They look great. No warning indicators though, thank god.

 

you can probably fake out the sensor by adding an appropriately sized resistor in series

 

i want to order the ones you have in blue should i jsut order them and give it a shot?

 

Got a reply from the store saying that I need a load resistor... so instead of going through all that hassle, I'm just gonna replace them with white bulbs.

Thinking of getting these: http://www.eautoworks.com/html/ORD-1-1-1-2067.cfm

However, I noticed that the wattage on these bulbs are 10W while the OEM stock one is 5W. Is this safe? Will the connector burn/melt because of the higher wattage? Please advice. Thank you.
