How do you replace a 3157 bulb?

To replace a 3157 bulb, first, ensure the vehicle is turned off and the key is removed. Locate the bulb socket, usually found behind the tail light assembly or headlight cover, and twist or pull the socket to remove it. Carefully pull out the old bulb and insert the new 3157 bulb, ensuring it is securely in place. Finally, reinsert the socket into the housing and test the lights to confirm proper operation.
