In 44,000 miles on my '02 Vulcan, I have replaced one right front turn signal bulb, and a halogen headlight bulb, when the low beam filament burned out in it, and the little warning light came on on the dash panel. I continued to use it on high for a couple of months before finally replacing it, because I was afraid the high beam filament would burn out too, leaving me in the dark.
As far a vibration, what vibration? My Vulcan 750 is probably the most vibration motorcycle I've ever owned, amazing since it uses a single crankpin. That balancer must be doing a great job. It has a slight rumble as low speeds, which goes away at higher speeds. And it lacks the "buzz" of an inline four.
A friend of mine with an '08 Dodge pickup had a tail light go out on him, it had a row of LEDs in it, and a circuit board, but it was a one piece sealed unit. fixing it required replacing the entire tail light assembly, at close to $300 bucks. If a tail light burns out on my '66 Ford pickup, it's a $2 bulb, and even the complete lens is $45, from a vintage Ford parts catalog, the reason it is so expensive is because it is a reproduction, and the price is proportional to how many they sell.
I have found it is best to stick with old technology, unless there is a REALLY good reason not to. Just because something is obsolete does not mean it is no good, it just means they don't make it anymore. Fortunately, I have a huge stack of catalogs full of obsolete Ford parts. Jerry.
BTW, Harbor Freight sells mostly junk, some of it is better than most of it. I have owned a Harbor Freight hydraulic engine crane for several years, and it still works fine. It has been used several times, not only for engines, but to hold up motorcycles (mostly dirtbikes) so I can work on them. I also have a drill and a 4" die grinder I bought from them several years ago, and both still work fine. OTOH, the cheap imitation Dremel I got from them lasted less than 2 months, while my real Dremel lasted 10+ years of abuse. I now own another real Dremel. Jerry.
