Underglow Kit Buying Guide

Installing an underglow kit to your truck, car, motorcycle or any other vehicle is fairly straight forward and cheap in most cases. They can provide you with partial or 360 degree lighting underneath your vehicle and make your presence known on the road.

Rewinding back a few years, most underglow kits were constructed of neon bulbs. They provided excellent bright light and were available in a range of color options. However, due to the advancement in LED technology, they are slowly becoming phased out with durable, bright and clever LED bulbs.

To help you make an informed buying decision, we have produced the below buying guide regarding underglow kits.

Neon vs LED

Neon uses old technology and have been used for many years in the car modification industry. However, are the days of using neon lighting over with the introduction of LED kits that provide similar level of brightness and more? To help you make up your own decision, we have discussed the features of each below:

Neon Kit

Neon lighting since contains a tiny amount of gas that is under light pressure in order to produce light output. This gas is stored in neon tubes that light up depending upon the type of gas that is under the pressure.

Installing the neon kit can be much simpler in some cases too and as long as they do not become physically damaged, they can even last longer than LEDs.

The main advantage that they have over the LED alternative is that they can be much brighter in some cases. However, the neon tubes are not the strongest and if they were to be subjected to heavy impact, they are more than likely going to crack.


Light Emitting Diode or what is commonly referred to as LED is by far the most popular form of lighting used with underglow kits. They are used for the majority of lighting that include LED headlight bulbs to inside your home.

When it comes to using LED lighting for the underglow kit, they are far more durable, which is great for those that use their vehicles for offroading. They also consume far less power, which reduces the drain upon your car battery and are cheaper to buy.

In terms of the installation, LED underglow kits can be installed in all the tight gaps and areas that may be subjected to impact, vibrations and dirt.

Color Output and Modes

An underglow kit is available as a single color or multi-colored system that can be controlled by a remote control or Bluetooth via a smartphone application. Multi-colored are the more desirable of the two but are more expensive for obvious reasons.

Many include extra features that go a lot further than simply switching it on and off. For example, you can sync the lights with the car audio, which will fluctuate the music based upon the audio. There are a whole range of other modes such as strobe effects, moving motion and so much more.

When it comes to using these different lighting modes, it is important that you abide by the state laws.

Controlling the Lighting System

The ability to adjust the color output or control the pattern mode is highly desirable. This can be achieved by using a remote control or the more advanced smartphone application, which are developed by the manufacturer and are specific to the kit.

Remote Control

Using a remote control is the old fashioned method of controlling your setup. They are easy to use and you have no worries of compatibility or the length of the distance you can control the system from. However, the remote control can be easily lost, will require batteries and may not offer as much functionality when compared to a smartphone application.


Bluetooth is the more modern approach to controlling your underglow lights and it offers more functionality. The manufacturer of the kit will have their own smartphone application that will enable the wireless connection. Once up and running, you will have complete control of the system and will have less wiring to install too. However, not everyone will want to use their smartphone and the issue of compatibility  may become an issue too.

Installation of the Underglow Kit

The majority of the kits available are plug and play devices that come with all the hardware in the box. Simply hooking the lights to the underbody of your vehicle and then using the cable to a suitable power source will have them outputting light.

However, not every kit will be the same and some may require additional steps to be taken. We strongly advise that you purchase some zip ties to help with the installation and ensure it is fully secure.


Installing an underglow kit to your truck, car, motorcycle or any other vehicle can improve the appearance drastically. They are easy to install and there are a range of affordable and premium devices available to suit all budgets.

All of our recommendations are suitable for a range of vehicles and can be controlled via a smartphone application or remote control. Underglow kits are an excellent upgrade but ensure that you use the system safely and comply with the state law.
