As I have said before I am not a real devotee of LED kits but this one is a prime exmaple and well worth the money.
It gave extra life to the waterfall decal in the topper and if you run the lights in blue white sequence it really adds to the original cascade effect of the topper.
The buyer who bought my WH20 was blown away by it...he came to pick up Judge Dredd after purchasing that first and left with it and the whitey 4 days later.
