OK, so this isn't 'exactly' about my truck but as I was planning on using H4 LED inserts in my Gen 1 I road tested Isincer H4 LED lights in my 2000 Lantra wagon. Low beam slayed - good penetrating white light that made the original H4 halogens feel like driving with Dolphin torches. Road signs and reflective white lines leapt out from a long distance. The high beam wasn't great though but with the lows as good as they were, they are acceptable as a trade off and they're relatively cheap. Been driving with them for about a year and had one fail. It looks like the body of the light got really hot and the SMD type LED's delaminated from the board. The LED inserts go into a spacer disc that fits like the mount for a standard H4 halogen. It probably isn't ideal but I am going to drill some holes into the spacer/mount to allow some air to flow around the body of the LED insert and hopefully reduce the heat being retained by the body of the thing (they do have a heat sink on the back of them with a small cooling fan but for obvious reasons they aren't very big or efficient)
