Every new car model that comes out today seems to have either bigger displays inside, or more of them altogether. The reason is simple \u2013 people become increasingly more dependent on their apps and services. On top of that, these screens can be used to display essential driving information. Things like navigation, speed limit, night vision, back-up cameras, etc. That is fine until you put the safety factor into the equation. Displays often take the drivers\u2019 eyes off the road, which can be extremely dangerous. Luckily, you can install a heads-up display (HUD) on your car and see all the essential information at the same time you\u2019re watching the roads ahead. A HUD may be especially useful the next time you go on a road trip<\/a>.<\/p>\n

Heads-up displays are honestly nothing new in the world of mobility. Fighter planes were equipped with these contraptions even in WWII to aid the pilots during battle. Today, most car companies offer HUD\u2019s as an option in their vehicles, but only in the premium category. They seem to be very slow, adopting the technology for their lower-tier cars, which is a shame. What makes that even more shameful is the fact that HUD\u2019s are very cheap today, even those with built-in navigation.<\/p>\n

What makes them cheap is the fact that they are straightforward to make. HUD\u2019s may seem \u201chigh-end,\u201d but the core of every heads-up display is an LCD screen and glass to project it to. Okay, there are some other things you need to know, and that\u2019s why we\u2019ve prepared this article for you. Apart from explaining how HUD\u2019s work, we will also tell you about the different types of these devices, and also about the best car heads up display kits available on the market.<\/p>\n

What Is A Heads-Up Display?<\/h2>\n

It is a transparent display that displays various information, including velocity, navigation, speed limit, current song, road hazards, apps, etc. The transparent part means that you can view it while driving \u2013 no need to take your eyes off the road. Thanks to that, HUD\u2019s are a much safer way to monitor everything about your vehicle and the road ahead.<\/p>\n

How Does A HUD Display Information On A Transparent Screen?<\/h2>\n

In a few words, it is a small display that projects information on a transparent screen. Car manufacturers use the windshield to project the information on, as it looks much better. Some aftermarket kits, on the other hand, display the information on a small glass part. The reason behind this is simple \u2013 the glass needs to have a unique film applied that reflects light better. Here are all the different parts that make one HUD system work:<\/p>\n
