I ordered 4 of the LEDs for my instrument clusters in the 240D and 300Sd from
www.vleds.com via their ebay store. Item #280176560432. Total price for 4 bulbs shipped was $24.77.
They made a tremendous difference in the brightness and illumination of the cluster. I also purchased some aluminum duct tape and lined the recess on the back of the cluster where the light mounts.
