These bulbs are brighter than halogen and costs a bit more. Changing burnt out bulbs is cheaper for those using LED fog lights and spotlights.


If you want fog lights or spotlights with a really bright beam, get HiDs. Installing HiDs can be more expensive with longer service life.

2. Which mounting location is better for any specific vehicle?

Planning where to mount the lights is very important to position the lights. Positioning the lights will set them with the best and optimal angle to diffuse the lights effectively. Another concern where to drill to make the set up very optimally. Putting it in the wrong place is not very smart and blocks the best light diffusion possible.

  • Slightly above the windshield
  • The sports bar or roll bar
  • The Side of the rear-view mirror
  • Front and rearview bumper

Placing fog lights or spotlights should be given serious consideration especially with the mounting method and location used.

4. Drilling can’t be avoided when installing off-road lights

Doing this is very precise with the proper drill bit size that won’t damage anything with this invasive method. Knowing how deep or how shallow it goes is important!

  • Map out and determine the point of the drill’s entry. Measuring all the holes made with even distances will make all the DIY work more presentable not haphazard!
  • Mark the spot using masking tape to avoid damaging the side of the lode. X-marks the spot will achieve precise drilling too.
  • Drilling should be done very carefully and precise because it can cause damage when done wrong. Retrieve the drill bit when it has entered the metal.
  • Do the same process for the other side and make sure everything is equally measured.
  • Don’t forget to touch up the holes with paint to avoid rust. Smoothen the edges as well for the drilled holes.

Do all these steps when drilling points to insert the wires for the lights to be installed.

5. Setting up the electrical layout for the lights

Here are the steps to get the layout organized for all mounted fog and spotlights. A relay and fuse holder will connect the lights to the battery. 

Step #1

Choose an accessible spot on your dashboard for the light switches that are accessible. Some drilling might be needed so be careful!

Step #2

Open the hood and choose a place in the engine where it doesn’t get that hot. If there is a hole near the spot, use it. Drill a hole for the relay or fuse holder to be used if it needs to move closer.

Step #3

Install a grounding wire that should be connected to a bolt for the grounding point. Preferably use a black wire to mark it as the grounding wire. Do this or else.

Step #4

Choose any wire for the lights to be connected. Get it and link it with an in-line fuse holder, then to a positive post near the relay. Connect the wire with the in-line fuse holder should it cannot be connected directly. The relay and fuse holder protects the cars electrical from surges that can damage the electrical system. 

Step #5

Wire the relay and fuse holder that is secured to the batteries positive terminal post. 

Step #6

Connect all wires from the relay and fuse holder to the switches by inserting it through the firewall hole in the hood. When the connection is soldered and wired so that the lights can be activated using switches.

Step #7

Secure the connections made, fuses, and tidy up all the wiring that connects to the lights. Make sure that water cannot enter and seal all the drilled hole. Use plastics to secure them inside and outside properly.

Step #8

Check all the wires and connections visually then turn the lights on to check. Proceed to adjust the fog lights or spotlights if they work properly. Adjust the installed light on the mounts, now all is done.
