Hi, I'm Mike from 1A Auto. We've been selling auto parts for over 30 years.

Hey, everyone. Sue here at 1A Auto and today we're going to show you how to change the bulb on a '03 Tundra, marker bulb and turn signal. If you need any parts for your car click on the link below and head on over to 1aauto.com.

Remove this screw. It's a Phillips head. Set it aside and then you're going to grab this lamp. Now, I like to use a body tool, but I don't have to on this one. So, just pull it towards you. And, there's the marker light. Push down on the tab and release the electrical connector.

Now, there's the socket. You're going to twist it counterclockwise and pull it out. That bulb should be a 3157A. That's for amber, an amber bulb. Replace it back in the socket. Line up the four marks. They're sized so you'll find it as it goes around clockwise. Lock it in. Reconnect the tab. Then I'm just going to guide it straight in.

Put these two tabs right there on that. Come on, there you go, there you go. There's this little key tab over here. Replace the Phillips screw. Just snug it down. It's plastic here. Ready to go.
