the old design was a fiber optic set up, semi bright at night and invisible for all intents and purposes during the day.
the new design is actually a bulb an h8 LCi set up, much brighter and daytime visible but still retains the yellow shade, we are working on that system too as most prefer white angel eyes in tune with their hids.
the ICE is a great upgrade for all models prior to 08's, completely plug n play and almost as bright as our chromium angel eyes all in a high powered never before LED setup.
feel free to contact me should you have any questions or to order a set at special UB ONLY prices.
