Never understood the fetish for LED dash lights
It depends on the application. They are an order of magnitude more efficient and can run cooler, so they last much longer.
Headlamp applications tend to run hot but still last longer then halogens and are very bright because they're efficient. It exposes the weakness of setting regulations on the wrong unit - Watts. I imagine they'll switch to lumens or lux soon, if they haven't already. They aren't type approved, though, and they're getting better at detecting them. I use the high pressure xenon filament upgrades from Phillips and Ring night from ABD. Love'em.
Interior lights also have wattage significantly less than the incandescent equivalents (about a fifth to a tenth), run cool and can last 100,000 hours (allegedly!) Having just had the kick panel, binnacle, radio and centre panel out it actually wasn't as bad as I expected... But the less often I have to do it, the better. In the summer I'm going to take the entire dash out, replace everything with LEDs and out it back knitting I'll be dead before any of them fails.
Another bonus is that reduced power consumption means you might not kill your battery if you accidentally leave an interior light on. My wife's tailgate didn't latch one evening and she missed it because she thought it was the delay timer ... It ran flat and that de-synced the immobiliser and BeCM. LEDs MIGHT have prevented that.
