First low and high beam pictures of the Pilot Nolden VP-3106B's:
And an H4 (I only had one on hand):
Thoughts...
These are early thoughts but I'm comfortable with them at this point. My early reaction is that the Truck-Lites and Speakers are very close and that we can't go wrong with either one. I give a slight subjective edge to the Speakers - their high beam is really impressive. I confess that I may be a little biased however as I've done a lot of reading and the Speakers have uniformly rave reviews.
The Speakers are more expensive than the Truck-Lites and I think it makes sense to offer both as they both performed well in my little test and they have both been well rated in the countless reviews I have read. I also tend to favor the two of them as they are made in U.S. (the Pilots are made in Taiwan and offered by a German company).
The poor H4 was at a great disadvantage as I only had one, but it's clear that the LED lamps greatly out-perform halogens as better seen in many other tests available online.
I leave for my volunteer job on the Oregon Coast tomorrow so I won't be able to do more testing for a few more days. At this point I'm comfortable enough to offer both the Truck-Lites and Speakers. I'll put pricing in the next post.
