While light of any kind can suppress the secretion of melatonin, blue light does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours).

What you can do

Use dim red lights for night lights. Red light has the least power to shift circadian rhythm and suppress melatonin.

Just for anyone that's interested in the actual science behind it

I always knew red was the best light on the spectrum for night time (from when I had a Chinese water dragon as a kid his night time light was red)

But I never knew that was why! Interesting stuff

Exa tly what Johnny said. Tracking or the coilivers fitted incorrectly. They could even be slightly different heights so jack it up, whip off the wheels and start measuring threads.

Well it was done at a garage... By mechanics... I dunno maybe the roads where abit slippery as well might be tje cause of it too... I dont think they are cheap coilovers... Know he spent 300 400 quid on the coilovers...

And i went with him to the garage for them to fit them up..

Can't say I have any experience of anything causing this other than torque steer but that's not the case here. It may well have been a slippery road but I would think even something isn't pushing right or somethin is pulling back on one side Orr the other of the car. Did it do it under braking?

If it was me I would check from my gear box to my wheels for anything visually not looking right (maybe there's a problem with the drive)

Next I would check my brakes make sure there operating right nothing sticking etc, could be that the front left caliper is sticking a little but it's not obvious under gentle acceleration as you correct the steering without knowing but then when you put foot down it causes the car to pull to one side

Don't know if that will be any help but sure it's worth a try?

Think the first post of call is probably tracking though as johnny said

Actually my front left caliper is sticking and it throws me towards a ditch when i let go of the steering wheel lol

Breaks are fine.. So is the drive..

A sticky caliper should only throw you under braking, shouldn't pull hard on acceleration

But the front left brake is always engaged

it can only be tracking and/or suspension really, there the only parts that effect steering

Well that's seized not sticky

Would the suspension problem not causes the car to 'drift' right or left and not too pull a worn top mount car do this

Pullin the steering wheel to left or right is more likely to be drive or steering..

Your right about the brake though that was just an idea

Depends tracking could be so far out on one side that the wheels are straight but she tracks left/right

Coil spring could be sliding out of place on standard top mount, this rarely happens because the pressure in the the spring is enough to hold it but under hard acceleration the front lifts taking some pressure away from the spring and top mount

The driveshaft doesn't really do anything apart from turn the hub forward and backwards, it's possible it's a worn cv joint but 99.9 times out of 100 a steering problem is suspension or tracking

A worn rack shouldn't pull either it should only make the steering less responsive


If it was a slight pull on the wheel it could be any of these

Was the tracking lads shes all sorted now..

Sad regret might have to sell the blue b as its hard for a 19 year old to have 2 cars on the road... :/

Whats your other car?
