I haven't tried any automotive LED lights yet, mainly because to replace the bulbs in most of my lights you have to dismantle half the car. For example, to replace a parking light or front turn signal bulb you have to begin by removing the front bumper. I think the rear lights are about as difficult. The joys of modern cars.
I remember the old days, when one morning I noticed a parking light was out on my car, replaced the bulb in the time it took to get one from the shed, then went to work and left the parking lights on all day. If I hadn't replaced that bulb I'd have been able to use the starter, but adding the load of that fourth bulb meant I had to push. Luckily, cars of that era were very easy to push start single-handed.
