So how to check if entity with classname "light" is enabled? I need to check that and if it's enabled - than turn it off.

Try to check pev_spawnflags with SF_LIGHT_START_OFF and if so execute Ham_Use on it.

wow, thanks, it really helped.

One more thing that isn't fixed - when I turn off the light I need to prevent it from being toggled. I tried this:

set_pev( pEntity, pev_targetname, 0 );

But, I can still toggle the light somehow.

Maybe its because I am trying to block light from being toggled NOT at round start or entity spawn, but on mid-round.

Edit. OK I tested my code again and strange things happened. If I test the code in cs_militia at the garage(where the 2 hostages are located), everything is working perfectly, but if I test it in cs_estate or in cs_militia at sewers, code is working as I mentioned above - light is being turned off, but I am able to enable it )

The fastest/easier way would be probably to set the m_iStyle (34) offset to a value < 32, so Use will have no effect. (a check is done with this offset if >= 32 in the Use function)
It should be fine if it's the game which provokes that, because a plugin could use directly pfnLightStyle and you would need to block it with FM_LightStyle I guess.
If you set a null targetname and the entity spawns, it will be removed.

PHP Code:

void CLight :: Use( CBaseEntity *pActivator, CBaseEntity *pCaller, USE_TYPE useType, float value )
{
    if (m_iStyle >= 32)
    {
        if ( !ShouldToggle( useType, !FBitSet(pev->spawnflags, SF_LIGHT_START_OFF) ) )
            return;

        if (FBitSet(pev->spawnflags, SF_LIGHT_START_OFF))
        {
            if (m_iszPattern)
                LIGHT_STYLE(m_iStyle, (char *)STRING( m_iszPattern ));
            else
                LIGHT_STYLE(m_iStyle, "m");
            ClearBits(pev->spawnflags, SF_LIGHT_START_OFF);
        }
        else
        {
            LIGHT_STYLE(m_iStyle, "a");
            SetBits(pev->spawnflags, SF_LIGHT_START_OFF);
        }
    }
}
