I went with
new harness, new hella housing and bulbs. I then added a set of Baja design fog/driving lights. I looked at the JW speaker but liked the look of the halogen lights (color temp & aesthetics for this older truck). I also like that the Baja design lights have replaceable lenses and they also sell rock guards if needed. I don’t do a ton of off roading but I’ve already had 2 rock chips on the headlights. I’m guessing the brick shape of the fj62 doesn’t help

Do you have to replace the whole jw speaker light if/when you get a rock chip?
As for performance, the h4 bulbs are incredibly bright on the new harness and if you turn them and the LED fog/driving on it’s crazy, not to mention you can select from a few different color temp and wattage bulbs that are also cheap. When I got my rock chips it was a 25 buck repair. I’m not sure of the lumen output of the h4 bulbs on the new harness but compared to the Baja designs LEDs they are pretty similar to my eye. The Baja designs LEDs specs say they make 3150 lumens and the JW speaker specs say they put out 2250 lumens.
