Unless you fancy looking at the "dancing lamps" in front of your vehicle while driving, you might quickly get sick of that annoyance.

However, this solution might not entirely fix the vibration issue, depending on the weight of the driving lamps.

Introduction

Installing some additional driving lamps (either for forward or reverse driving) is on most people's wish list.


Warning Icon.pngInstalling additional external lamps on a vehicle might be illegal in some regions of the world, or may require that the vehicle goes through some recertification process.



Two possible mounting points for the driving lamps are either somewhere on the roof, or somewhere on/around front or rear bumpers.


Lamps mounted on the roof

Gen3-100x100.jpg


Gen4-100x100.jpg


Since most Jimnys 3 have factory longitudinal roof rails, the best way to mount the lamps on the roof is to attach any universal transverse roof rail(s) onto the longitudinal roof rails and then mount the lamps on transverse roof rail(s).

Since Jimnys 4 do not have longitudinal roof rails, they require the use of purpose-built transverse roof rails (their feet must be made especially for Jimny 4) and then mount the lamps onto those rails.

In any case, a DIY solution is required to install the wiring from the engine bay or from the passenger cabin all the way up to the roof, as neither Jimny generation has a factory preparation for any sort of wiring on the roof.


Advantages of roof mounted lamps:

  • You can install many (up to ~10);
  • They can be mounted either on the front end of the roof (for illumination when going forward) or on the rear end of the roof (for illumination when reversing).
  • They do not restrict air flow to the engine;
  • They do not pose a hazard to pedestrians in the case of collision, so they have more chances of being legal (but check with your local laws);
  • No need to drill or glue anything to vehicle's body;
  • They look prominent on the vehicle;


Disadvantages of roof mounted lamps:

  • They increase air resistance during high speed driving;
  • They may induce significant wind noise during high speed driving;
  • They might get damaged if they tangle up in low branches when driving through a forest;
  • The need to carry something else on the roof might be hindered by the presence of the lamps on the roof;
  • They give off a prominent glare from the bonnet, reducing your forward vision


Lamps mounted on or near the bumpers

Gen3-100x100.jpg


Gen4-100x100.jpg


If you want to mount the driving lamps on/near the bumpers, you have a problem that both Jimny 3 and 4 have modern soft plastic bumpers. They are inadequate to be mounting holders for the lamps, because they are not sturdy enough.


Rear bumper

In case of the rear bumper on Jimny 3, (very small) driving lamps can be installed only in the bumper itself (by cutting a hole in it somewhere near the rear lamps). Mounting anything on the bumper is out of the question, unless you don't plan to open the rear door ever again.

Info needed in case of the rear bumper on Jimny 4 ...


Front bumper

Inside the bumper

In the case of the front bumper both on Jimny 3 and 4, it is not advisable to mount anything in the center bumper hole where there is a factory ventilation grille (except for very small lamps), because that might severely restrict the air flow towards the engine heat exchanger (improperly called "radiator").

In the case of DDiS Jimny 3 with 63 kW K9K 266 diesel engine (2006-2010), it is also not advisable to mount anything in side ventilation grille holes in the front bumper, because that will restrict the air flow towards the intercooler which is positioned just behind the right side ventilation grille in the bumper.

In the case of a petrol Jimny 3 with 2nd gen. front bumper (2006-2012), installation of additional lamps in side ventilation grille holes in the front bumper should not incur significantly negative effects regarding proper engine cooling (apart from possibly looking ugly), it is a viable option.



In front of the bumper

Read the chapter on nudge bars further down below.


On top of the bumper

One simple solution (in theory) is to simply drill two holes on the top of the bumper (in front of the hood) and mount the driving lamps on the bumper itself. However, as the bumper is made of thin plastic, it vibrates and wobbles during driving, and so will the lamps that it would carry. Unless you fancy looking at the "dancing lights" in front of your vehicle while driving, you might quickly get sick of that annoyance in your field of vision.


The vibration issue can be remedied by one of two methods:

  1. Reinforce the top of the bumper (from the inside) so that it becomes thicker / stronger / stiffer and does not vibrate and wobble. This is typically done by applying one or two layes of special plastic net soaked into thick epoxy resin (that's what vehicle bodywork restorers do when they fix damaged plastic vehicle panels). However, this solution might not entirely fix the vibration issue, depending on the weight of the driving lamps.
  2. Fabricate and install / weld your own metal mounts behind the front bumper, which would hold onto the chassis. The mounts should end right below the top of the bumper. Then drill two holes in the top of the bumper just above the mounts. This will enable the driving lamps to be screwed into the mounts, and the bumper will have no weight bearing function whatsoever. This solution has been proven as a stable platform in practice, and completely eliminates the vibration / wobble issue. However, any future removal of the front bumper requires prior removal of the driving lamps.
  3. Buy ready-made or fabricate your own metal L-mounts which attach to the slam panel behind the bonnet grille and hover above the front bumper. Then attach the lamps to those mounts.
