There are several different Wipac led kits as well. Some look silver inside when you look @ them when not illuminated and have fewer leds. Some have more leds and no silver reflective surface inside the lamp base.
The higher the led count inside the better the outward appearance imo. Have fitted a couple different customer supplied sets but haven't found the "right ones" I want yet.
FWIW the same wipac kit is 30 quid/$45 cheaper from Paddocks http://www.paddockspares.com/standar...ear-lamps.html
Tempted to try a set of the RDX slimlines from Bolt On Bits in Yorkshire.
They also have several/5 different lines of led's for Defenders.
Liking the slimline with plinth version
