Problems with Your Mazda Protege Headlights
The Mazda Protege was popular small family car that was produced in great numbers from 1963 up to 2003 making it one of Mazda's longest running nameplates. Over the years, some owners of the Protege have reported problems about their vehicle's headlights. Common issues was that the lights were very dim at times or would flicker on and off. Since headlights would only last for a couple of years before you need to replace them, then it's best to learn to troubleshoot simple problems with your Mazda Protege headlights so you could do some preventative maintenance.
Most folks who are experiencing weak headlights may have a couple of problems that they'll need to check. First, lights need to be powered by your vehicle's battery and alternator. So if there are any problems with these two components, then they'll definitely affect the performance of your vehicle's headlights. If you've checked that both the battery and the alternator are fine, then you'll need to bring out a multimeter to test the wiring of your vehicle's headlights. Don't forget to check if the connectors are plugged in tight, since they can come loose over time. The worst case scenario would be that the bulbs inside the headlights are already starting to wear out, so the best solution would be to simply replace the headlights instead.
Low beam headlights have stopped working
Your Protege's low beam headlight would probably wear out faster than the high beams since you use them more often. Once they stop working, you'll want to check out a couple of things before outright replacing them. Apart from the tests mentioned above, you'd also want to check if you simply blew the fuse for your headlights. Open your fuse box and locate the fuse for your Mazda Protege headlights. If it appears burnt out, then simply replace them and check if your headlights are working properly again. Once you've checked all of these, then you'd have to take out your headlamps to see if they're already burnt out and would need to be replaced. Most headlights should be replaced every two years or once they start to show signs of wear and tear. You wouldn't want them to suddenly fail entirely while you're driving in the middle of the night.
