LED Lights/Bulbs, Projector Vs Reflector Headlights

Headlights can be defined as machines that help see the road at night or in the dark. Earlier, these headlights had a rudimentary mechanism, but they have witnessed a lot of advancements with time. Now, these headlights have a lot going for them, from different categories to different working mechanisms. So, today we’ll focus on the two major configurations, reflector and projector type headlights and which of the two support LED bulbs better. Because it’s the era of LEDs, and the market is loaded with aftermarket LED bulbs.

Working

Both reflective and projector share the same basic principle to spread light on the road. But these two types differ in the way (or the apparatus) they disperse light.

Reflector Headlights

The simplest type of headlights is the reflector type. This is where the headlight assembly consists of a bulb situated at the focal point of the reflector. Now, as the bulb is turned on, the light from the source spreads all over the shiny surface of the headlight. Now, because of reflection, the light beam is directed towards the road.

Projector Headlights

Similar to the reflector type headlight, projector headlights also have a reflective inner surface. The difference lies in what’s after this surface; yup, it’s a projector setup or, in scientific terms, a lens. The bulb emits light; it is spread all over the reflective surface. But instead of beaming the road haywire, the projector does its job. This lens precisely disperses the light on the road for better visibility.

Let’s dive a little deeper. The markets are loaded with a plethora of aftermarket headlight bulbs for you to install in your vehicle. Apart from the category of bulbs (H4, H7, H8 etc.) and headlights, the type of bulb also matters.

  • Nowadays, depending upon the variant, cars come equipped with projector headlights. But it isn’t necessary that a car also gets a led bulb, it can also be the conventional halogen bulb. (eg, Tata Nexon)
  • Next, there also are cars that get reflective type headlights and still get led bulbs. (eg, Honda City and Hyundai Verna)
  • Then there are cars that get a projector set up and also get Led lights. (eg, Maruti Suzuki Vitara Brezza)
  • So, this clears that majority of the car’s headlight choices revolve around the configuration wherein they get, a reflective type headlight or projector headlight and Led light/bulb or a halogen bulb.

If your vehicle has a projector light setup, it is highly recommended that you upgrade to a LEDs

  • Why? Halogen bulbs are not bright enough.
  • Also, they don’t use the full potential of the lens. Hence they are not efficient when compared to LEDs.
  • Installing LEDs on a projector will make the headlight more effective.
  • Because the LED bulbs possess the diode at specific places, the entire internal surface of the projector will focus the majority of the light onto the projector.
  • This will result in a better and brighter beam of light, in turn aiding your visibility at night.

Now, if your vehicle possesses a reflector type headlight, it’s better you go with the flow and stick with halogen bulbs.

  • The majority of the aftermarket bulbs have the diode on two or a maximum of 3 sides.
  • Meaning the light is not spread evenly. This is something that is a big downer when installed in a reflective type headlight.
  • For a reflective type headlight to be effective, the light source should emit light evenly.
  • But if you are talking about the high beam in the halogen, sure, the bulb is designed to spread the beam in a particular direction.
  • Also, the reflective area of headlight housing is specific to a halogen bulb.
  • Even if you do happen to install the LED bulbs to reflective headlights, firstly, you’d be blinding the oncoming traffic (even in the low beam).
  • Next, the light will not be focused but scattered all over, hampering your vision at night. Which is hell a lot dangerous.
