No BLIS unfortunately.
Good design though, very visible to other motorists, peds and cyclists.
OEM halogen stupidly are all red instead of yellow blinkers.
Mine (exact same) tore off too, not sure how. There's one bolt. Picture shows part number. I found a replacement for about $6 on ebay including the bolt and clip.
I understand OP's frustration but I also think it's a safety issue. I use ACC every day for my commute in heavy stop and go traffic. If OP (or a family member) borrowed my truck and turned off ACC, I DEFINITELY need a warning. Otherwise I'm going to rear end someone or at least scare the crap...
Maybe Autostop Eliminator could make a product to force recirc to stay on. It works perfectly on the Autostop.... It would plug in behind the switch and make it "sticky"...
Same specs and very similar usage as me. OP, I dropped from 18.5 overall to 17.5 on regular gas just by switching from the stock Pirelli to Continental tires in the same size. I'm not surprised you're losing more than that with HD tires and a level.
