hello guys do you guys know what size is the high beam for the 2011 tc thanks

 

check your owner's manual.

 

search engines are there for a reason. this took me literally less than 15 seconds to find. faster than posting a thread about it.

usually that is the answer to this question 99 times out of 100, but if you didn't notice, this guide does not go up to 2011, and the 2010 tc and 2011 are the difference between the 1st and 2nd generation, so it might not work.

but again, i say, OWNER'S MANUAL! or pop out your high beam, look at the bulb itself.

 

9005 according to manual.
