My headlight bulbs have been replaced and checked 2x by the used auto superstore which I will not name at this time ! and by the manufacturer (dealer) but once it’s dark out and the automatic brights come on and either both or one side goes completely out only to come back on sometimes or not at all which is very dangerous especially at night !
