The lights both went out..do you think it's the bulbs or wiring? they have never been changed

Should be think about replacing the circuit board?????? If you don't know how to test electrical circuit's using wiring diagrams an diagnostic testing equipment you really should be thinking about what qualified repair shop to take it to .

Does your car have the `lamp out'indicator system? It's more complicated.
My manual shows fuse #28 , a 15 amp fuse powers the brake bulbs.Is this the one you changed?
A bulb can be out for a long time and you don't notice it,then the other burns out and you think they both went out at the same time,but they might not have,see?
So check the bulbs and make sure you got that brake switch installed correctly. don-ohio (:^)

if you touched the glass on the bulb with your fingers or hand in any way then the oil from skin would make the bulb burn out after a short period of time also some of these aftermarket bulbs are junk. i do not think in any way that you have any fuse or wiring problems.

I dont think the fuse would blow, I would change the bulbs

You got a bad ground connection somewhere.
You have a voltage drop,where you shouldn't have,and as a result the bulb is dim.
Check the bulb socket/connector and related wiring, to that head light

Don't try a higher fuse , it just makes things worse by adding extra burn to the problem.. First make a test lamp with a 21w bulb ( indicator size) .You now have a bulb with two wires attached , insert the "test bulb" across where the fuse should be.
When you switch on the circuit concerned it will glow BRIGHT as it is getting a POS (+) and a NEG (-) ie blowing the fuse (short circuit) in the fuse box and therefore a BRIGHT bulb.
As you disconnect and eliminate or disturb the problem the bulb will immediately glow DULL ( in series contact now) and no longer a short circuit . As you check the circuits the illumination will change and, your on the money ! Let's know how you get on , Good luck

check the bulbs.mine were changed and some genius put wrong bulb in and i had exact same problem as you.make sure tail/brake bulb has double steel connectors.my drivers side one had bulb with single connector,i put new bulbs in both sides and problem fixed.hope this helps mate

sounds like you put the wrong bulb in, that will make it blink fast. re check

Fuse should be under dash on left side. Providing that there is power there and power at the signal switch (and bulbs are good) likely there is a problem in the signal switch.

Some times when you get a short circuit. It will burn out a tail light bulb. With the bulb burnt out you don’ have a complete circuit. First, replace you tail light bulbs. If that doesn’t work. Check to see if you have a ground wire come off.
