Buyer’s Guide: Amazon Car Accessory Deals
Shopping for automotive accessories on Amazon can be overwhelming because there are so many brands. Here is a quick guide to the most popular items we track and what to look for.
Jump Starters & Battery Chargers
Gone are the days of needing another car to give you a jump. Lithium-ion jump starters are the most popular item on this page. When looking for a deal, check the “Peak Amps.” A small sedan needs about 400-600 amps, but if you drive a diesel truck or a large SUV, look for deals on units with 2000+ peak amps.
OBD2 Scanners & Diagnostics
Stop paying the dealership $100 just to read a code. We frequently find promo codes for OBD2 scanners ranging from simple code readers to advanced bi-directional scan tools.
Pro Tip: Check if the scanner offers “Free Lifetime Updates.” Some cheaper units charge a subscription fee after the first year, while the deals we post often include lifetime software support.
LED Lighting & Off-Road
Whether you are upgrading your halogen headlights to LED or adding light bars to your Jeep, fitment is key. While many of the off-road lights we post are universal, headlight bulbs are specific. Always use the “Amazon Garage” filter at the top of the product page to confirm the bulb fits your specific year, make, and model before using our promo codes.
