I agree with Justwondering.
I buy bulbs by the box of 10 – which are SO MUCH cheaper than a package of two (for almost the same price). There are four different vehicles in my fleet, that are used daily – so what I have done is purchased a clear bin (I’m guessing 15” x 24” x 12” tall, going by memory) and keep all of my bulb boxes in it.
I also printed off the different bulb numbers on MS Word onto printer paper, and placed 4 different pages into the same box.
When I need to replace a bulb, I grab my bin first, look at my sheet, grab a bulb out and place bin back by garage door shelf.
Then get ‘em replaced.
Headlight bulbs – I have a few in another clear bin – but nothing elaborate about it. I do purchase headlight bulbs in pairs – but keep the spare in box until needed.
Actually, “I” only replace the bad bulb – except for dash cluster bulbs or any that are excessively hard to access.
Bulbs do not all go out at same time (in my opinion) – and I have replaced thousands of them (maybe even more than thousands).
A couple of tips:
- Avoid touching bulbs with bare fingers – for oil from fingers can shorten the lifespan of some bulbs (plus it is harder to push light through fingerprints).
- Get a touch, or bit, of wheel bearing grease and place a thin layer around the bulb base. Most grease will conduct electricity – unless you get dielectric grease (which does not). Most bulbs do use the round base as an electrical conductor (ground) so something there does help with corrosion – but be careful of too much of a good thing can cause a problem.
- Boxes of bulbs are cheaper still, from internet (or from eBay). Matter of fact, some bulbs – you can get Halogen versions (on some bulbs) for about the same price as normal bulbs at an auto parts store.
