PIAA H4 Lamps for Thunderbird, Tires

Which H4 lamp have you used in your Thunderbird, and what kind of life did you get out of that lamp? Did you need anything other than the lamp to install it? The standard low beams are between poor and terrible and I wanted a suitable replacement.

As an aside, I decided to get the Ultra 2 Avon 200/50/17R as my replacement tire for the Thunderbird. Keeping the front Metzeler for awhile, still looks good. The Metzeler is a very good tire, but 5-7k does NOT cut it for me. That, plus mounting has lead many a rider into the poorhouse. Avons generally have a better center section and longer tread life, compared to Metzelers. May consider the Avon Cobra front. Anyone been using these two Avon tires, and if so, what is your experience to date?

I stayed with the Metzelers with my first replacement set...we'll see how that goes, but if they don't last more than the originals (I Had been riding the whole time with too low PSI...hoping that makes a world of diff) But if you're having good luck with the AVON's, I'll absolutely consider them on the next set...because I absolutely agree, the 5-7K mi on the metzeler's won't cut it, for sure! Keep us informed of their wear/tear!

I have the Sylvania Silver Star Ultras. They improve the low beam a bit, but not as much as I had hoped. I've pretty much given up on improving the standard headlight. The high beam is fine, but the low beam is terrible.

I ended up adding motolights and they help a lot, but are pricey.

I've mentioned this before I think, but does anyone like the look of the dual headlight on the Storm and Rocket III Roadster? I was checking out the mounting bracket on the Storm in the showroom the other day and the lower portion that mounts to the forks is the same as the Tbird - the upper part of the bracket is different that hooks to the lights itself - not sure about the wiring and the plug because when I brought my tool box in to remove the tank they stopped me for some reason. I'm going to make the dual headlight happen sooner or later just because I like the looks - but I'm sure it can't make low beam performance worse - should be some better!

I'd switch to the dual headlight if/when they offer a chrome version.

I have a few hundred on the avon now and so far i like it a lot. absolutely zero issues using that and the metz up front, and the handling is at least as good if not better. Actually it seems to feel a bit better planted. The straight line stability at speed seems better too. This is all fairly subtle, but mileage is going to be the big thing. And being a dual compound and having deeper tread should insure better mileage. the question is how much. At least one guy has 8k on his and says it looks around 1/2 done. If mine does 8k total i'll keep using it over the metz.

I'm happy with my decision and even tho my front seems to last quite a while, i will likely go with the cobra when that metz goes. then again avon is talking about a set for our bike that includes the current ultra and either the cobra up front or making a storm in out size. Not sure which and they seem unsure too, but i've been communicating with a rep from the UK plant and he says he will be looking into it and getting back to me once he's back from vacation. I will post what i find. in any case i think the avons are the better tire and i'm sure they will outlast metzeler, just not sure by how much.

What pressure are you using in the Avon? I ended up using 40-42 psi rear and 38-40 psi front, seemed best for my weight and the 812 pounds of the SE. I kind of laugh, Triumph listed about 756 or thereabouts for the SE. With the windscreen, footboards, sissy bar and luggage rack and bags, plus ABS, it weighs right at 812 pounds wet.

Engage,

Did you install them yourself? If so, how long did it take? Were the motolight instructions easy to follow? I saw your pictures and they look great.

What if there were no hypothetical questions?
