I have found that the brighter, or higher-performance bulbs have much shorter lifespans. The Long Life bulbs may be more robust, but aren't as bright as the high performance stuff. To extend the lifespan of the main headlight bulbs (I've been using Sylvania Silverstar for decades) on my 2008 Forester, I disabled the DRL feature. My thinking is mostly along the lines of reducing the number of on/ off cycles, as described above. Also. Avoid handling the bulbs with bare fingers..the minute amount of your body's oil and fluids in your fingerprints is not compatible with the super hot glass bulb. I prefer the 5 mil Harbor Freight Nitrile gloves for this job. Just my 2 bucks

Take a picture with a cell phone, then enlarge it. Or use reading glasses if you have those. After 40 years old a high percentage of men start to loose close up/small detail vision and the percentage gets higher with age after 40. It would be surprising if you haven't lost close up fine detail vision. modern bulbs suck in terms of robustness. I think "higher end" bulbs can have better characteristics - brightness/perceived brightness, clarity, color, pattern, but sacrifice longevity for it. So you might actually be better off buying cheaper ones depending which ones you're looking at. I generally look for ones that favor longevity which isn't always easy to figure out since that doesn't seem to be the dominant concern. I *think* LED's are the preferred option for longevity but even that, I don't know which ones are quality verses marketing hype. I think GD has posted which LED bulbs he installs? Maybe? If so - he's probably installed a lot of them and has a much better view that those of us just replacing a few here and there. A friend designed circuitry to keep power supply consistent to lights on big rig trucks to keep the bulbs from blowing as often. Their lifespan was drastically improved. The electrical inconsistencies - temporary spikes etc are what fatigued the bulbs. I would assume that is at least partially true for automobiles as well. And I wonder if daytime drivings light are more susceptible since they're always on when turning the car on/off and engine start up - etc. They see all the instantaneously loads or electrical changes commensurate with those electrical moments. Just speculation but keep your power supply fresh.

Hey Paul. Was this you and your aging eyes? blind corner.mp4

This ended up being a wheel bearing.

I believe there may be a Philips bulb with a suffix -LL . supposedly for long life.

That adjuster looks pretty rusty, you might want to considering ordering new ones as they are relatively cheap and easy to replace. Last time I did my drum brakes both adjusters were seized and the square drive strips super easily. Also as a tip, one of the easiest ways to adjust it is using 12 pt 1/4 drive 7/16 socket and flipping it around to use on a 3/8 inch drive ratchet.
