Oh no, youve just wasted some money mate. Theyre crap. Youll find yourself having tubes that dont work after a few weeks, or a month if youre lucky. Theyre exactly the same as the £5 kit you can buy from taiwan or singapore, forgot where now. The light emitted from them is piss poor, you dont get that much glow from them at all.
The side neons dont need to flash, they can stay on all the time.
Can sell you a proper undercar led lighting kit, but theyre like 10times more expensive than what you paid (£475), but you get a lifetime guarantee plus loads more toys and functions with it, like 2.1 million colours.
Fitting tubes is really easy too. Mount the side tubes next to your chassis box (sill?) and aim the tubes at a 90 degree angle, so the leds are in a direction like \ Thisll help hide the leds a bit as the circuit board will be helping to block the light, yet still shine on the floor (if theyre powerfull enough). Front and rear are really easy to do, no brackets needed for these, if the bumpers are the same as mine, you will find holes already in your bumper underneath (on the white part), just shove some cableties through them. Will take pics to show my setup if you want tomorrow
Also, make sure you put your switch in an easy to reach place. Cops will and do pull you over quite often if youve got them on. Although the lighting is a grey area of the law, they can still give yo a whacking fine and make you mot your car and stuff like that. Ive not had a bad cop pull me over, the ones that have pulled me up have just wanted to see more of what my kit does. Use them in a carpark, you wont get fined, use them on the road and be a paranoid driver
