Morning all,
I recently changed my interior lamps to LED's and they are so much better.
Just a thought: Are the centre console controls lit by a fibre optic bulb?
If so, is there any point in fitting an LED bulb in there to brighten them up a bit? (2007 MY)
Just wish it would help with readability during daylight hours...... Any suggestions?
Thanks in advance.

Isn't there an issue with the electrics when you change the bulbs over to LED. I thought they started to flicker after a while because of the different electric current or something????

Has anyone had them changed for quite a while without any issues??

A few weeks after I fitted LED bulbs in all the interior lights the driver's door puddle light started coming on for about a second at regular of 30 sec intervals when the door was shut. Replacing it with an original halogen bulb cleared the problem.

I have had LED's in all the interior lights, footwell and puddle lights, and boot lights for months with no issues.

Flickering is usually a sign of a failed LED.

Depends on the actual LED's used.

I think there is a current issue where the control modules NEED to see a current threshold.

Higher quality LED's are fitted with current limiting resistors to protect the LED and also a current drawing resistor to present the car with enough draw to fool the brain boxes.

Cheaper ones or faulty ones won't have the desired effect.

I imagine it would be easy enough to simply fit a resistor across the supply to one of the flickering LED's and see if it cures it.

Ohms Law would be your friend here ;-)

GTDB7 is spot on correct ......
