I have an NB8B, and after watching
this from YouTube, I went and ordered a pair of the
Auxbeam 9006/HB4 for the low beams and a pair of
Auxbeam 9005/HB3 for the high beams.
And I have to say, the performance are just amazing. Perfect for the projector style low beam lights of the NB8B. They really provide a sharp horizontal cut-line with the light projection, avoiding dazzling incoming cars. The reflector high beam provides a deep and wide spread in front.
For over 10yrs I'd had a pair of Bosch HID lights for the low beams of my NB8B, and they've been terrific. But with the advancements of the LED bulb technology, IMO LEDs now surpasses HIDs.
LEDs are instantly bright, unlike a second or two that takes the HIDs, plus they have a smaller footprint within the car. LEDs with built in drivers (just like the Auxbeams I got), are essentially a plug and play affair. Compared to HIDs with their additional wiring and ballast - which was great to remove from the engine bay, when I switched over.
As mentioned, I've had the same HID kit in the NB8B for over 10 years and they've been extremely reliable. I just hope with these LED bulbs with their built-in cooling fans, will be just as reliable. Cooling fan reliability is probably the unknown quantity in this bulb. Fingers crossed they don't fail early.
I've had them in my car for a couple of months now and I'm happy with their performance so far.
