Yesterday, I was having to clean some corrosion off the control board on my ML550's blower fan assembly.
Having finished cleaning the fan's control board, and about to hook up the leads to the passenger side's courtesy light (foot well), I looked at the 5W 12v Festoon Bulb used for the courtesy light. see pic attached, below.
I had some LED lights on hand, and decided to see if the LED's bright white colour looked better than the Festoon bulb's yellow glow.
So, I installed the LED bulb (see pic attached, below).
I opened the door to activate the passenger side's courtesy light and, WOW!, it looked soooo much nicer.... especially with the interior's black appointments. :grin
What I didn't expect, was an added bonus by using the LED.
When I went for a test drive (to test the blower fan) the courtesy LED bulb dimmed right down, as did the driver's side festoon bulb, but the LED didn't fully turn off. :eek
Instead, the LED light stayed on, dimly. The effect was wonderful. :smile
I took my wife out for another test drive, when it was completely dark outside.
She saw the nice bright, white, foot well light up when she opened the door and got in, and then as the interior lights dimmed off, she saw her foot well stay dimly lit.
She loved it!
It is similar to the soft glow of the interior lighting scheme on our 2012 ML350, that stays on with night-time driving.
The soft dim of the LED did not distract, or interfere at all, with my night-time driving.
We both liked the look so much, that I am going to install the same kind of LED on the driver's foot well, today.
One last thing, in using these LED's, no fault message flashed on the Console.... that was good, too!
Hope this may be of interest.
