I recently replaced all my bulbs with LED. I've done relays in the past but LEDs are better.
On a side note. Instead of the typical fast blinking issue that is well known when replacing bulbs to LEDs, I experianced a no or slow blinking issue. All I had to do was replace the flasher with an electronic flasher. I've seen people refer to them as low load but I believe they just called them "electronic" when I went to Auto Zone.
The result is less load on the switch and as a result less on the fuses.
Also....buy red or amber color for the brake lights, white bulbs make the red lens look kind of orange.
