Hi All
We too were frustrated with the ARB foggies: weak, unsealed + fill with water and dust, used only once in 5 years (not too much fog in WA).
So, we removed those ARB fogs and replaced with 120mm LED spotties from Jaycar. That's an extra 3400+ lumens per side that we didn't have before.
There was some jiggery pokery to get them in. I reckon that hubby and were on the job for 3 hours.
We cut away the black plastic housing of the arb fogs to make way - and made up some simple brackets to hang the new lights off the chassis.
A bit of re-wiring, and its all good.
The new lights work fine. Not blindingly stunning, but certainly a noticeable addition.
Some folk reckon that spots aren't worth while placing at that level (too low compared to the driver's eye level). We reckon that hasn't affected us.
The new LEDs are only 230mm below the line of the car's lights (normal beams and IPF spots / spreads). As the cruiser is 2" lifted, these lights wouldn't be too much lower than other installations.
Anyway, what we wanted to say is: yes, it's possible to swap out the arb fob lamps with spotties.
