I have two LED indicator lights on my 2006 E350.

• A small red LED on the left inside edge of the dash.
• A yellow LED on the front of the right edge of the dash.

I don't know what they are for. I could find nothing in the manual or online about these. Help!
The small red one will, for some unknown reason, start to blink at different rates. There is also a chirping sound when it blinks.
See the attached photos.
Any pointers on what they are for, and why the red one blinks and chirps, is very much appreciated!


Unknown RED LED blinks and chirps apparently randomly - what is it for?


Unknown Yellow LED is on - what is it for?

I am guessing you bought USED.
Previous owner added something like alarm or performance thingy or ??
and these things have these red and yellow LED lights

decorily

Some kind of homemade parking sensors?

I agree with ygmn - the placement of those lamps does not look factory.
