Hey Dave!
Not sure your status on this, but i want to recomend my friend Reggie at Roversplus.com. He is in Middle TN, a little north of Nashville and he has the best prices i have seen yet. He is also a great, straight shooten guy who loves to work on only LR Discos. He's got parts galore, too. Last time i went to see him he even took me muddin in his back yard to find a part for me.

 

For the headlights there is a small white light inside the fixture next to the headlight bulb itself. Looks real dim like you said but it isn't the headlight.

Could be both low beams within the bulb are out, high beams work and you think lows work but are just real dim.

Change both headlight bulbs. Does cost but they need to be changed from time to time and it might solve the mystery for you. If not you know the bulbs are good.

 

Man, what a thread necro!
Everything except Amigos is fixed, including Mike's 60k, and I live in Las Vegas now!

 

see if you can find yoursel a USED RSW amigo for sale. they retail at $200 i bought mine used on here for $100. also keep an eye on other land rover forums 'for sale' sections. it comes in handy to just own one if you plan on keeping this truck.
