2021 Mountain Aire Taillight

[MiKaLo]

Does the MA have separate turn signal/brake lights or are they one bulb doing double duty,

I had to look up a pic. Surprised my DS has led lamps and the nicer MA doesn’t appear to. From the look of the tail lamp id say it is a multi element bulb. Like a 3157 or something. I can’t ID the taillight. But if you know what passenger vehicle it is borrowed from, a good guess would be they share the same lamp.
sorry I’m not more help.

My 2017 Ventana uses two lights stacked, it was from a pickup truck that was used that I recall as I had to order a replacement. Can you post a picture of yours? Also please complete your profile by adding your RV info when you have time.
