Mitsubishi Eclipse GT 3G (6G72) weird light issue

Mitsubishi Eclipse GT 3G (6G72 - 3.0L V6) at about 145,000
Since like summer of last year, right now is the third time this has happened (and will probably correct itself eventually like the other two times). Every so often, a light, either front or back, will just decide not to work for a while (like for a fairly extended period of time, maybe a few weeks). The first time was a taillight, then a turn signal, now a headlight. It only seems to do it one at a time, seemingly random which one it picks to do, and the weird thing is it then eventually turns the light back on on its own like normal, without me needing to do anything to get it that way. It's been a while since the last one too.
Clearly not an issue with the actual lights I'm sure as much as something electrical behind it, but I wouldn't have any idea what, and I'm just curious to figure out what could be really going on with this weird issue and what I'd have to do to fix it (before I get fined by an opportunistic state trooper).

First - what model year is this thing? Age matters with light bulbs but self correcting isn't helping for just a bulb if that not likely to correct more than once circumstance and that bulb fail and stay failed soon.
Check the sockets and if one is corroded from exposure frequently from the back you really should check them all.
Same for anyone common bulbs, brake, turn signals, headlights if known age from new and original if one really blow do both sides of the same if old enough do up them all using bulb grease as indicated. BTW - see that sold and called that at assorted places but know the word for it is dialectic grease - quite simply not a word people use very often,

It's a 2004, and I haven't had it the whole time so I can't say when exactly they were replaced last. I don't see any damage or corrosion right on the connectors, so that's good at least, but you're saying then basically that for these potentially pretty old bulbs that if I put a bit of dielectric grease on them that should be all they need to work fine and not switch off (I've never heard of it before so that's why I'm just making sure)?

OK - it just happens to some or many. Bulbs are or supposed to be greased when car made new - varies how well. Back sides of them also exposed and you are old enough if you didn't waste (not a waste) spend a weekend chasing every one with spray grease AND exposed to some or lots of rock salted roads or was even a couple times before you got it the fuse it lit for them to go in many ways.
Bulbs can especially higher powered ones be undependable at even the 5 year area if used. Have a ton of 100,000 hour LEDs in other things don't last that either so that's a lie and another story.
Bulbs with a filament (glowing hot metal inside) worse if they blink have to be cold then very hot - all weather extremes plus moisture have everything against them. They usually look a bit discolored to look at them even when still working.
Nothing changed over a zillion years except most are worse new than much older when they were new. I do all now and then and still one or more goes out.
The only part that's unusual to me is more than once one doesn't work then works later by filament - sockets can do that more often - caught when not working just touching them with dry paper with a wiggle test the socket or connection, wire on some bulbs and all are usually the culprit.
Add to that any power surges of voltage thru car can also be a nightmare on anything electrical bulbs show up early if so. Bad enough on my own vehicles watch real voltage with a cigar lighter volt meter always there to know when or if running voltage isn't staying in range and warns me of excessive voltage drops.
Mechanics or not I don't want this crap by surprise for myself either - we drive vehicles too!
