Funny, Daniel Stern (lighting.mbz.org) likes Philips Premiums (aka High Visibility in US-DoT HB1/3/4/5 format), Vision Plus and the Osram/Sylvania equivalents. And when it comes to automotive lighting, bulbs etc. that guy really, really, REALLY knows his s#|t. Most reviews that I've read also praise the clear (not blue) versions of these bulbs. Istr the Hellas weren't rated quite so highly, but remember, Hella doesn't make bulbs, they're just rebranded third party manufacturer products. I'm not sure who the original maker is of the Hella bulbs, and that may well vary by bulb type. Daniel Stern would have all the finer details. Some of them may be good quality; others may be cheapy back alley Korean or Chinese junk.
A multimeter always helps; it certainly picked up the bad connection at the high beam splice to my driving lamps. But I really slapped myself on the forehead going "Doh!" when I found the source of this problem because it was so glaringly (npi!) obvious. In fact I had already had a tentative hunch by the process of logical deduction that that is where the problem was, yet I didn't have the common sense to check there first, instead going off on wild goose chases checking the connections, voltages and currents *inside* the car under the dash! But then, I'm just a bittuva dummy, I guess. To the following question:
In Bigtown, 7% of telephone subscribers have unlisted numbers. If I take 500 people from the phone book at random, how many of them will have unlisted numbers?
...I originally thought the answer was 35, but someone apparently told me it wasn't. Oh well, I might figure it out some day... and so many people call me "bright", "smart", "clever" and "extremely intelligent". If only they knew the difficulty I have with questions like that one, they might rethink their position. Maybe (decimally)
7% of 500 isn't actually 35 as immediately sprung to mind, but I didn't think I was all that bad at math. ;)Connections, sockets, relays (if applicable), electrical system generally... all worthy of a quick inspection.
