Hella Optilux H4 100/80W Xenon White XB Kit (Pair)

Best holagen bright white clear bulb these 80 dim 100 brights are amazing for an old glass lensed 2000 4runner I bought the 100 watt he dogs to match since I have offroad lights on my ram guard so I bought 3 sets which is 6 bulbs and I got these for my head lights so I have 8 matching bulbs the light output is amazing bright easy to see clear nice whiteish blue huh more white than anything else best light out of hundreds of bulbs I have tried very much recommend

There is a clear distinction between the normal H4 bulbs and the Hella Optilux XB. Zenon always burns brighter. That's how strobe lights produce their intensity. After a reasonably long life, one of my low beams died and I bought this new set. After replacing just the one bulb, I noticed that the newer bulb is even more in the blue range than the last set that I bought. A very noticable improvement for an already great headlight bulb.
