Yeah, I only have about 3000 of them in the field. What would I know?
Yes, we've had failures (with nearly 3000 in the field, that's to be expected), but the % rate is very low. FYI that customer was going to go with Liberty bars 5 years ago, but 50% of the test bars leaked badly enough that they failed. Those were brand new Liberty bars, installed by the big Whelen dealer here. A factory rep came up from Whelen and told the customer that they had never seen a Liberty leak before.
The failures in the field that have occurred with the Legend are easily repaired. The part # is right on the board, and anyone with a screwdriver and a socket set can change it in 10 minutes. I've had gas station techs
in the far north change these boards with no issues. The field serviceability of the bar is excellent. Much better than sliding a pile of lenses out to get to the module you want, then reassembling them, making sure you don't fold or pinch a gasket, etc.
