I just got the lows and highs for my 08 4Runner. I can only compare them to the basic Sylvanias I have been using but I am impressed with light output. If they last at least a year, I will be very happy with them.
I guess this method can be considered easy peasy but I still manage to make a big mess tonight.
Be very careful that you put the hose from the funnel into the nipple on the top of the radiator. I got it backwards and spayed nasty burnt transmission fluid all over the place.
I used 1/2" clear...
