Any Traffic Orificer who knows the law to the letter, will be able to give you a fine, or even declare your car unroadworthy if your lights do not carry the relevant certification. This applies to globes as well, specifically the globes in head lights and auxiliary lights. So as long as you can find that E certification on the light, your only worry then, would be that your mounting position is correct. So, LED lights that carry the E certification, can be used, but those are usually the expensive ones.
My son purchased his brand new GD6 Fortuna, and Toyota themselves put a factory fitted lightbar behind the bumper. Two weeks later, on his first business trip with the car into Namibia, they gave him serious flack about the lightbar. Fined and had to be removed before he could carry on. This required the removal of the bumper.
Some notes on legal placement of auxiliary lights, where placement height refers to the center line of the light...
Lights need to be symmetrically placed from the center line of the vehicle, (which thus excludes mounting an uneven number of lights)
Lights may not cross the center line of the vehicle (such as in the case of a light bar).
Lights may not be mounted above the level of the head lights of the vehicle.
Lights may not be mounted behind the vertical position of the headlights, such as those found on Jeeps next to the windscreen, and hence also excludes lights mounted on the roof.
Lights must only be able to work while headlights are on bright, and then also be isolated by a relay and a separate switch.
Out of interest, your vehicle headlights may not be higher than 1.4 meters from the road surface, so watch your lifts
. This turned out to be the only criteria my traffic chief was worried about when I did my lift on the Sani. Old Hillbilly's headlights ended up at 1.1 meters, so they were happy, lol
