2005 prius hatch back keyless problems and low beam on one driver side

i have a 2005 prius got it 2 years ago when it hade 120,000 miles now has 211,000 runs good but last week on my driver side the tail light and low beam light stopped working at the same time the high beam works fine what could it be?

my keyless was working fine tell this week went to pick up a reptile and i locked the doors while the car was running went into a store and came back out keyless didnt work i thought it was the battery because i had to get closer and closer for it to work latly so i went to advances auto parts got a battery put it in and it still would not work i put it into slot went about my day because iv had alot to do the last few days and when i got out later in the day i forgot it wasnt working and used it and it worked i got home and shut off car went in came out in the morning and it would not work again does anyone know what could be the problem normal wear and tare oil changes all that have been done ever 4 to 5000 miles havent been to dealer because iv got to do for the next few days still

 

new battery for the keyless remote not a new 12 volt but i was told by the dealership when i got the car it had a new 12v battery put in

 

i think advances auto parts checks battery's for free i can stop by one while im out tomorrow and have it checked and post back with if its good or not if its not good ill replaces it while im there

 

Tested battery at advance they h ade the car off hooked thing up to 12v battery says its good voltage 12.49 measured 355 cca rated 325 cca temperature 43 f
but when they checked i notest about 4 inches of frozen water down in the places where battery is and about 2 3 inches up on battery sorry about that phone auto spell kills me

 

Auto spell on my phone missed It up I corrected it

 

Cool do u think that could cause the problem the water being down there on it

 

I checked around on here the battery test was done right should have gotten one while it was on but it has tested good also I can use key to get into the car and I can put fob into slot and start car

 

okay so I replaced the battery again and now my car will walk but it won't unlock and if I walk up to it just opened the door unlocked but my own lock button doesnt work and I can push the button to start the car and it works outadvance would not refund me on the first battery thatdid not work

 

Hole unit or just bulbs thought it weird that they both stopping working at the same time

 

someone was directing me out backing out on the road and regular beam headlight went out same time as tail light its was my brother he was like dude your tail light and head light went out

 

thanks for the information and I'll get back to you and let you know if it worked
