OK,

i successfully brightened up my dash lights in my 124 by using... drum roll please... fine sandpaper!!!

the 124 dash uses this clear plastic piece which directs the light from the bulb to shine to the dash. the slightly curved part at the end of the piece is where the light eventually ends up, thus illuminating the dash.

what i did was i sanded this part to dull the surface, effectively "frosting" the area where the light "exits"... this more effectively illuminates the dash because most of the light gets "trapped" in the frosted area... (diffusion?)

i don't know if i used the correct terms but trust me, it worked for me.

you can try this on a small part of the plastic thingy, you'll notice that the dulled part will show more light
