A car horn is essential for alerting pedestrians and other motorists of your presence, and can help prevent serious accidents on the road. Little do many motorists know, but it’s a legal requirement to have a fully-working car horn, and a faulty or nonexistent horn will result in a failed MOT. A car alarm is designed to alert you when someone is attempting to get into your vehicle without the use of a key. Most modern cars are equipped with a basic car alarm, though third party alarms are the most secure and offer the highest level of protection. At Halfords, you’ll find a great selection of third party car alarms for all car makes and models. What’s more, our high-quality car alarms will also reduce your insurance premiums, so it’s definitely an investment worthwhile. If your car alarm keeps going off, there’s a chance that it may be faulty or has been fitted incorrectly. For a professional fitting service, head to your local Halfords Autocentre and speak to a member of our team for more information. To find suitable car alarm systems and horns, enter your registration number into the tool provided and our system will pull relevant products for your vehicle. Once you’ve found the products you need, use our convenient click and collect service to get hold of them sooner. Alternatively, opt for delivery and have them delivered to your home or work address.
