If the headlamps are on and the light switch has no affect, either the switch is faulty or you have a chaffed wire somewhere making the relay pull in.

The fifth generation Isuzu Elf appeared in July 1993, with more sculpted headlights.
In May 1995 it received a minor change, including upgraded, cleaner diesel engines.
An OEM deal with Nissan led to the Elf also being sold badged as a Nissan Atlas and a Nissan Diesel Condor 20/30/35 beginning at this time, followed by the Nissan Atlas Max from 1996 until 2000. The Atlas Max was based on the new, lighter duty Elf 100 (June 1995) which was available with a 2-liter petrol or a 2.5 or 2.7-liter diesel engine.[20]
In May 2004, subsequent to a few minor changes, the Elf underwent a more major facelifts with new, larger, trapezoidal headlamps.
Another OEM deal was forged at this time and the Elf was now also marketed as a Mazda Titan in parallel.
In Malaysia, this truck is manufactured by Heavy Industries Corporation of Malaysia (Isuzu HICOM Malaysia) under the name of HICOM Perkasa, but carrying the Isuzu N-Series Commando badge.
? 100ft/lbs is a good guess, but is but a guess.

buy book at any Isuzu heavy truck dealer.

nor what country , other countries use different radios.
