Well your question is an oxymoron. Cheap lights suck. Simple as that. However, if you're seriously trying to keep it cheap, any 2pc headlight and some Philips Extreme Vision bulbs are going to be the best you'll get.
I am curious about this too. Just bought my 12 truck used at dealer knowing one headlight had moisture. My ******* told them no don't worry about headlight just take 400$ off bottom line. The previous owner put these lights in. I have Had the truck a month now and both have moisture in them. Lol. Shud have told dealer to fix cuz they prob wud have had to put in oem lights in. But also i didn't know anything about headlights then. Seems that cheap are bad. I might try dtmoto. I know they are not liked by some... but money tight.
