KC HiLITES Lights - 50 Series 4-3/4" Round

Our popular 50 series lights measure approximately 4-3/4" round and are available in long range, flood, and fog patterns with chrome or black chrome finishes. With the changes to automotive lighting during the past two decades, there has been a major move toward the use of halogen bulbs as the light source. This technology has proven to be superior to incandescent sealed beams in that the halogen produces a much whiter light and has added more life and efficiency to the bulbs. Anticipating these changes and feeling that the halogen is indeed superior to sealed beams, we have begun replacing our sealed beam lights with high performance halogen units as well as incorporating improvements developed by KC HiLITES, such as tougher filaments and higher wattages. These changes are being made to attain superior performance and maintain a long service life, which are both essential for our customers. Our first units to feature these changes are the off road, long range models as well as our newly re-designed flood lights. Also available are approved fog and driving units for maximized performance.

Types of Lighting: What's the difference between the types of light patterns?
We basically have 4 different types of light patterns: Driving - Flood - Fog - Long Range
The differences between these patterns can be viewed on our Lamp Applications page.
KC Hilites Wiring Questions:
Does the white wire have to be connected? Yes, the white wire has to be connected to a 12-volt source.
This circuit allows the switch to activate the relay, which draws power from the battery to the lights. If you do not want your KC's to be activated with your High or Low beam lights, then you can use your fuse box or your battery as an alternative 12-volt source.What is covered under warranty?  We proudly warranty all of our products against failure for a period of 23 years. If a housing or reflector begins to rust, if a switch fails, if a cover fades from the sun - we even warranty all of our bulbs against burnout.  Exclusions are abuse and damage caused by accidents.  See our Warranty Statement.
What is the Amp draw of my KC lights?  Amp draw is a simple mathematical calculation. Divide the total number of watts by the system's volts. For example, a 100-watt bulb in a 12-volt system will draw 8.3 amps.
(100w / 12v = 8.3a)
What is the purpose of using a relay?  Using a relay keeps the high current portion of the circuit away from the switch and pulls the current directly from the battery to your KC's. The relay also allows you to tie your lights into a secondary 12-volt circuit such as your high/low beams or ignition.
Identify Your KC Lights: How do I identify which lights I have?  Most all of our lights have the letters KC and a 4-digit number on the Lens, which can be used to identify which type of light you have. By comparing the shape and size of your light to the light Series pictured in the Replacement Parts section of our web site, you can select the matching Series and find the 4-digit Lens number in the chart to determine which light you may have and the replacement parts available for that light.
