Today was opposite day. Went ***** shooting and missed the first THREE birds. Decided to put an LED light strip I bought for the rear (can't put it in til the rear is fixed from the crash) as an under-hood light. Drilled the switch mounting hole off which caused it to bind so I decided to drill it out. Drill caught which caused the switch to spin into two pieces. Prepared another switch, laid out my wiring and then forgot to install the woven wire cover over the wiring before I crimped the connectors. Decided to put the + ring terminal on the right hand fuse block stud and couldn't find my 10MM SOCKET. Wife brought home paper work for a new FORD EXPLORER!
Four Roses was not involved...until now. :rolleyes:

Ordered some LED headlight bulbs from Amazon. Replacing the Phillips higher output bulbs. They seem to last about 2.5 years. Thought I'd give the LED jobs a try

Limited-time deal: SEALIGHT 9005/HB3 H11/H9/H8 LED Bulbs Combo, Super Bright Cool White, Plug and Play, Pack of 4 https://a.co/d/cz0HN8E
Get these in yet?

this is the one you want, bought mine in 2019, price has gone up about $30 and they take 6-8 weeks or longer to build and ship.
or you could go with a GM GENUINE 84143539
gm started making them like the mechman design with pressed diodes
it's actually for a k2xx 2500 but it will fit and work and is about $100 less than the mechman and is only 30amp's less

You'll end up returning them. I threw on a "great" set of leds maybe 2 years ago. They were definitely much brighter but only to about 15 feet infront of the truck. They lack distance. Huge no for me. Bought some ss3 fogs instead and havent looked back

Are these high output alternators a simple replacement or do other parts need to be replaced to account for the extra output?

plug-n-play, they do recommend upgrading the cable from the alternator output to the battery, I believe I changed mine to 1 gauge and added a 0 gauge ground wire from the alternator mounting bracket to the frame.

HID's are the way to go if you want good light output, but to do it properly you need to use relays direct to the battery and just use the headlight positive as the trigger.
otherwise you can get either get intermittent operation and/or melt the headlight fuse (over time). just have to take my word for it I have ran HID's for 20 years or more before they became a "thing". Otherwise LED's have to be the absolute highest output you can find and be adjustable
