I would say I'm 79 and LED's are the only way to go. There should be charts out there for replacement LED's for your make and model 4 Runner on the internet. I feel someone on this forum should be able to help you with this. Do make sure you get the correct LED's that will work with your 4 Runner, some LED's do not work well with some models, this is usually caused with the computer and how it reads the voltage of the lights, etc.
