Rear Fog Lamp Assistance - 1997 SL320

[Arctic1]

Greetings All

This is a relatively minor issue, but still would like to clear it up.

My 97 SL320 has the rear fog lamps. While testing them I noticed that the left lamp is much brighter than the right lamp. Decided to investigate and noticed that on the left lamp both elements are lit, while on the right lamp only one element is lit.

Swapped the bulbs from left to right and again had the same result with the right side only having one element lit.

This has me puzzled as I am assuming its a contact or wiring issue but thought that there would have only been one wire leading to the lamp contact.

Any suggestions in regard to this? I can offer clarification if my overly wordy post is confusing.

Thanks
