If you are looking for a cheap self-contained low-voltage esp-8266 based relay module suitable for vehicle use etc, then do an ebay search for...
"Remote WIFI Wireless Control Switch Module Precise DC5-24V"
(Set Side bar settings to 'Buy Now', Worldwide', 'Free P&P')
Results typically cost under a fiver, but I've seen it as little as £3.99
Although not listed as such, it is actually a Sonoff SV (Safe Voltage) relay module, which is easily flashed with Esp-Basic - it will work directly off any voltage from 5v to 24v, and also offers pin access to gpio 5, 4, 14
