The iconic headlights and taillights of the Land Rover Defender are a design feature that endured for over 70 years. 

For owners undertaking a Land Rover V8 rebuild, choosing whether to replace like-for-like or upgrade lights is about preserving the car’s history and authenticity.

What is the history of the round lights on Defenders?

The Defender followed on from early Series I, II and III models, which had their roots in practicality and post-World War II austerity. Lights for the Land Rover Series had to be functional, robust and cheap. 

The headlights and small dome-shaped taillights were easy to seal for weatherproofing, and from the 1940s to 1970s, round lights were common and produced at scale. 

Very early models had 7-inch circular headlights in the front grill to protect them; however, this limited their usefulness. For the Series IIA onward, wing-mounted headlights became the standard factory fitting.

This was partly to comply with new motoring standards in the US requiring a minimum distance from lights to the edge of the car, and partly to improve their effectiveness. 

Why did Defenders keep the round lights for so long?

The simplicity and functionality of the headlights and taillights on the old shape Defender could not be denied. They were, and still are, easy bulbs to source and replace for servicing. 

Despite many car manufacturers switching to boxy, rectangular headlights in the late 1970s, Land Rover did not follow the fashion. The heritage of the classic design was retained, although 7-inch sealed-beam halogen lights replaced the older versions on Series models. 

Why did the new Defender shape have different lights?

In 2020, Land Rover launched the all-new Defender, a redesign with a sleek, modern exterior. Among the many changes made were the external lights. 

Gone were the distinctive round headlights and the tiny round tail lights that had been part of the aesthetic for decades. Instead, Land Rover installed bigger tail lights that were flush to the bodywork, in square-shaped, albeit with rounded corners. 

The headlight retained an echo of the circular lights of old but was redesigned to suit a 21st-century road car’s needs, powered by LED rather than halogen bulbs. They gave better visibility, and the new models had daytime running lights too.

The light assemblies also made them more complicated and more expensive to replace than old bulbs.
