Has anyone identified OBD error-free LED bulbs that are short enough to fit in the W211 mirror puddle lights? The truly error-free LEDs I tried are too long to fit. The shorter ones that did fit were not really error-free, even if they claimed so.

It is odd how each eBay seller who falsely claims their LEDs are error-free immediately gives you a refund if you describe how the car flashes the bulbs every couple of seconds. No questions asked, no explanations offered. No apologies for the hassle either...
