Don't Waste Your Money On Light Bulb Grease

    Have you ever needed to change a light bulb in your car? You probably went to the local auto parts store and asked for a new bulb, then watched as they hassle you into buying useless light bulb grease. Do you really need it? Will it help? Will it hurt? Do you have the extra cash? These questions came up and turned into a loud argument at the local auto parts store with my friend refusing to be taken for a fool.
    It all started when my friend from work had a taillight bulb out. Since I do all the maintenance to his 2007 Camry he asked me for advice. It took me literally twenty seconds to ask him to pop his trunk and remove the bulb. Then I sent him to the auto store and said, "Get one of these. Two if you can afford them. And don't get the grease, you don't need it. It should cost you about four dollars.". He took me on my word and proceeded to the store where he got into an all out verbal confrontation with the clerk.
    He called me and said they didn't have a single pack. He was tight on money and wanted to know if there was another store closer with single packages of bulbs. Regrettably the other store was about four miles away and simply wasn't worth the trip. Then I heard the argument. Apparently the clerk thought no one in their right mind would sell single package tail lights. He is wrong. Plenty of stores do. Also without my friend knowing he tried to slip in the useless light bulb grease for two dollars more. A few unfriendly words later and the clerk was strong on his opinion I was an idiot for telling my friend not to buy the grease. This is Memphis. My friend very forcefully told him where he could go and how to get there.
    Anyhow this story happens all over the country and don't let it happen to you. You do not need any light bulb grease, it will cause harm in the long run. The main purpose behind light bulb grease is to prevent corrosion on the current bulb and ease replacement for future bulbs. The problem about shoving a gel substance into an electric socket is that with time is becomes thick and causes problems. I've changed many bulb sockets because of the grease thickening and shorting out the terminals within the socket. This may only be a fifteen dollar fix to replace the harness, but it may cost consumers one hundred dollars to have their vehicle replaced at a dealership.
    Light bulbs go out about every two years in the real world with driving habits of the modern busy person. Corrosion is not a problem in this scenario. With properly sealed light fixtures corrosion should never be an issue. Therefore you can rest assured if you don't use the grease then you won't have corrosion problems because there is generally never a corrosion issue. I have seen it before, but only in leaky fixtures where water is continuously in the area. Light bulbs are also very easy to remove without needing additional help by the lubricant grease. If you need help changing a light bulb strength wise then I don't think you need to be changing a light bulb. Never the less you can still know the process and not become one of the millions of consumers who buy needless items because someone says they need it.
    To make a long story short, do not buy light bulb grease and put it on taillights, headlights, or any other light bulb in your vehicle. It will cause harm in the long run and just waste two dollars you could use on something else in your life. Don't let the clerk at the auto parts store pressure you into buying the light bulb grease that you don't need. This is just my opinion though.


  1. I have a turn signal that gets moisture for some reason (probably when I wash the car, moisture accumulates on it). I have two options, buy a better socket that does not let in moisture, or spend a bit of money on the grease. Choice is totally up to the consumer, though, and no one should be "pressured" into buying it if they think they don't need it.

  2. Thanks for making this post. I moved from Europe to the USA and before coming here I never heard about light bulb grease in my life. Nobody in Europe is using it and nobody has any issues with light bulbs in their cars. Here, every car parts store is trying to sell you one, and convince you that it's necessary.

    Also, I didn't know 30$ halogen headlight existed. Previously I was buying bulb spare kits with one piece of each bulb for the car between 5-10$. Check it out: http://www.amazon.de/UNIVERSAL-ERSATZLAMPE-KIT-H1-SICHERUNGEN/dp/B007BE4XQU/ref=sr_1_4?ie=UTF8&qid=1451449202&sr=8-4&keywords=spare+bulb+kit Very weird not to find such a combo here.

  3. Automobile manufacturers use grease on the light bulb connections to prevent corrosion. You of course can choose to use it or not. Do expect more corrosion related issues if you don’t use it, especially if you plan to keep the vehicle a long time.

  4. Your not actually supposed to put it on the contacts..if you do that of course your going to cause more issues. Your supposed to put it around the entrance to the housing and around the rubber silicone. And it will prevent moisture from getting in the the bulb thus preventing corrosion

  5. Finally I’ve found your blog, awesome way of explaining each and everything really.
