So I just replaced all the interior lights with LED bulbs, in a 2001 v70, and now they won't come on when I turn on the car, until I take out fuse 24 and 28 and put it back in. Some will turn on but it seems like after a while the computer recognizes low volts and shuts them off. But other times they will just stay working for the entire driving period. Is this just an issue with the bulbs I bought or should I be looking for something else? They're all 41mm 16led - I was thinking probably should get 36mm 6led but I'm not sure of the error.

 

It's fairly apparent many LED products were rushed to market.
Were questionable or cheap batches of LED elements dumped on the market?
Were time slots on idle assembly lines spottily made available to people hustling inadequately designed junk to market?

Some LED lights run real hot, others not as much. Heaven only knows what their electrical characteristics are like.

Contact people who've posted successful results with their own LED installations and buy what they did. Search other cars' fora as well. Many use a CANBUS system.

There are companies frequently identified with selling proven kits of LED lamps for specific cars.

There's "no percentage" in addressing a problem caused entirely by the use of funny lights.

Not to be mean or dismissive: restore the original incandescent lamps and try the LED route again with proven products from reliable suppliers.

 

Thanks man, I get the tone. I got a batch of german made led's and there's np with em. Appreciate it!
