Home Cadillac


Cadillac was founded by the Henry Ford Company in 1902 and was named after the founder of Detroit, Michigan – Antoine de la Mothe Cadillac. It was among the first automotive luxury brands in the world. It was then purchased by General Motors in 1909 and remains a division of the American automobile manufacturer till date.

Prior to the purchase, Cadillac was amongst the first car brands to introduce some of the latest technologies. These include a steel roof, complete electrical systems, and clashless manual transmissions. Its V8 engine set the pace for the American automotive industry.

The brand’s major market is the United States. In 2017, Cadillac sold 156,440 vehicles in the U.S. and 356,467 vehicles worldwide. Other markets include China, Canada, and 34 additional countries.

Finding the right replacement for your fog light or headlight is one of the most important things to consider when replacing your light bulbs. The right replacement size can take time to find. However, with a headlight bulb replacement guide, any professional mobile electronics installer or newbie Cadillac enthusiast can save a lot of time.

Whether you’re merely replacing a factory bulb or upgrading to a high-intensity discharge kit, a light bulb size guide makes the process easy. As always, it’s advisable that you confirm that all the bulb sizes, bulb wattage, and voltage usage are appropriate for your vehicle. This should be done before putting the information provided within the guide into use.

A replacement bulb guide is meant to provide general information only. The required bulb type or process of applying for your vehicle may be different. As such, headlight bulb replacement information providers are not liable for any errors encountered within the guide. It’s advisable that you consult your local car dealership, a professional or your vehicle owner’s manual for the appropriate bulb type.


Having clear visibility on the road is an important safety measure that all drivers are required to adhere to. Damaged and ineffective lights interfere with the entire lighting system making visibility poor. This then inhibits the ability to spot obstacles – a situation that could mean life or death.

You can easily install off-road lights on your Cadillac or replace the existing headlights. However, before upgrading to HID headlights, there are a number of rules and regulations that control the lighting installed on cars. These regulate the light type, color, and size. Proper lighting ensures that all vehicles provide sufficient visibility for not only the driver but also the oncoming traffic and other motorists.

There are a number of aftermarket lights available for your Cadillac. Replacement and performance lights vary in quality and depend on the manufacturer.

Some of the reputable manufacturers within the industry today include RI, Sylvania, Spyder, Lumen, Eagle, and Spec-D. Products vary in size and are built to meet all your Cadillac needs. With the right product, you will not find yourself battling traffic or standing in line.
