I have been putting HID kits in all my vehicles for years (so far my 99 Vette, wife's 12 Wrangler, my 12 Ram, my 09 Raider to name a few). I have never had a problem until I put one in my Vaquero. The output on low beam would intermittently flicker, even with a canceler in place. I tried replacing the bulb, the ballast, even the wire harness, nothing worked. Then last night on my way to work it just dies altogether.
Long story short, I had one of those new
H4 LED bulbs (no ballast or crazy wiring, very plug and play) from xmas and had been waiting for a chance to put it in. Now I had a reason, lol. Heres the
link if your interested.
I after watching some install videos, I took the shield off the bulb before I installed it. The results were awesome! I get the same light output I did with HID, better light spread, and instant on (no waiting for the warm up period). And none of the crazy wiring mess.
Look into it if your thinking of upgrading from Halogens.
