The bulbs on these cars are mostly standard, and you can find replacements all over Amazon. With LED bulbs, you tend to get what you pay for, as most are junk made as cheaply as possible. Good LEDs will last foreverish, bad LEDs will die from vibration and what not, possibly in weeks. I try to buy Philips stuff or any other reputable brand if I can.
I have these for my tail/brake lights:

They light instantly from the brakes, draw nearly nothing from the electrical system, and have good visibility from all angles.
