The streetlights in Las Vegas are terrible, why?

I live in Las Vegas, but can only speculate.

1)  Las Vegas Strip is actually in unincorporated Paradise Nevada and north Strip in unincorporated Winchester NV, both managed by Clark County.We prefer low property taxes. We have no income taxes. There are overpasses at key intersections and barriers at many corners trying to keep pedestrians off the roads. The few crossing points at street level should have traffic lights. Modernization is expensive.  There are also trams and shuttles and walkpaths away from the street. A lot of public works projects compete.

2) Traffic Management handles it

They last studied pedestrians and did a 2015 update

They focused on many improvements to keep people OFF the streets, but include a change to LED lighting, whenever that happens.

3) The pedestrians are generally hit in jaywalking, crossing or walking highways and major roads, and the fact that drivers hitting them are often visitors who are not used to high density. Not sure brighter lights would help much on-Strip at least. The casino displays put out fairly bright lighting. Drunk and lazy pedestrians?

I have been to Vegas many times.  The lighting has never been an issue for me.  Drunken morons stumbling blindly on the other hand are a rather larger problem than the lighting at least.
