does anyone know if a bad flasher relay can cause your bulbs to burn out?
like, if my bulbs blink too fast, i might need to replace both my bulbs and flasher, not one or the other?

Wrong bulb in the socket. Replacing with the correct bulb should make the flasher behave normally. Or so I've heard.
------------- Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

that is how the problem started. i've put the correct bulbs in and replaced the flasher. i still can't figure it out. i haven't replaced all at the same time though, that is why i am wondering...

Normally when your side markers are flashing faster then they use to, it is because one of the filiments have burnt out.
If you replaced them with LED style lamps, then the internal resistance is too low.
Lastly, if the actual lamp has been replaced with a lower wattage bulb with a single filement instead of a two fillement, it too will cause the same effect.

this is what happened. the problem is that the effect seems to be permanent even after the correct bulbs have been installed. any ideas???

The very first thing I would do is verify that ALL four corners of the vehicles lights are indeed fine, and operational.
Normally, side markers are wired in pairs, but I have seen some vehicles where all front and rear are tied into one circuit for what ever reason.
If your vehicle has upper and lower markers, again, you must ensure all lights which come on during hazard engagement are indeed working, do not simply rely on the fact that they are blinking.
That only tells you they are passing current, not whether they are consuming the correct amount of current.
Let us know when all the bulbs have been removed and checked.
The only other then is a failing flasher unit, not very common, but it does happen.

ok, so today i bought 4 new bulbs, a relay and a multi-meter.
the wires & sockets all physically looked fine. i check voltages and they all seemed to have a good 12V. i noticed one of the sockets in the front had a piece that was a little loose. it was the metal piece the bulbs connects to. the lights worked though, so i don't think that is a big deal.
then i changed the bulbs, relay and crossed my fingers. apparently the realy wasn't the right one, because there was not blinking. i thought all three pronged ones were the same, but maybe not. then i put the old relay in, same problems, nothing new.
so i guess i will try to return this stuff to the store and bring my car into my local mechanic next week to check it out.
i've got no more ideas.

The standard is a 552 flasher, a 537 flasher will allow you to flash more than one circuit.
