Something to be aware of with regards to LED bulbs is that there can some issues with dual intensity bulbs and how noticeable the changes are.

For example, most cars have brake light bulbs that when the lights are on, turn on at low intensity and flash at a higher intensity.

Since LEDs really only have 1 brightness level, this has to be given a workaround where at low intensity, only some of the LEDs are lit and at high intensity, all of them are lit. If the difference between low and hi intensity isnt very significant, or the effect is muted by way of tallight lenses, it can be hard for the cars behind you to tell if youve appled your brakes or not. This same effect can also be a possibility when talking aobut side marker lights that also act as turn signals.

I dont have 1st hand experience with this, but I know poeple who do and felt uncomfortable enough to switch back to traditional bulbs.
