The headl amps can be quickl y removed for bul b repl acement due t o t he uni que 'Rail Lock' s yst em. Headl amp acces srequires t he removal of 2 bol ts securi ng the headlamp to the bonnet cl osi ng panel . A l ocking l ever at t he rear of theheadl amp can t hen be li ft ed, releasi ng a l ocking tab at t he base of the headlamp body. The headl amp can then be pul ledforward on the rail and, aft er di sconnect ion of t he harness connect or, removed from t he vehi cl e. The 'Rail Lock' s ys t emensures that t he headl amp ali gnment i s not compromis ed duri ng t he removal proces s .
Each headlamp has two access covers at t he rear. The larger cover requi res t he l ocking l ever t o be released from i ts gui des lot s to allow acces s to the cover. The cover can t hen be removed by rel easi ng 2 t abs to al low the hi gh and low beambulbs t o be changed. The circular rubber cover i s a pus h fi t onto t he rear of t he lamp ass embly. Removal of t he cover givesacces s t o the si de lamp and turn s ignal indicator bulbs .
On NAS vehicl es , t he s ide l amp is col ored orange. The s ide l amp lens i s desi gned so that li ght from t he s ide l amp bulbals o i ll uminates t he orange colored reflect or area at t he s ide of t he lamp wit hout the need for an addit ional bulb.

Safet y Precaut ions
The fol lowing safety precauti ons mus t be fol lowed when worki ng on t he xenon headlamp sys tem:
DO NOT att empt any procedures on t he xenon headlamps when t he li ghts are s wit ched onHandl ing of t he D1S Xenon bulb mus t be performed usi ng s uit abl e prot ect ive equipment, e.g. gloves and gogglesThe glas s part of t he bulb mus t not be t ouchedXenon bul bs mus t be dis posed of as hazardous was teOnly operat e t he lamp in a mounted condit ion i n t he reflect or.
W ARNING: T he Xenon system generates up to 28000 volts and contact w ith this voltage could lead to fatality.Make sure that the headlamps are sw itched off before w orking on the system.
Headl amp Cons truct ion and Funct ionali ty
The xenon lamp or Hi gh Int ens i ty Di s charge (HID) lamp as they are s ometi mes cal led, compris es an el li ps oidal lens wi th as olenoi d control led s hutt er to change t he beam output from low to hi gh beam.
• NOTE: If the l ight cont rol module rot ary s wit ch is in t he OFF pos it ion, the xenon lamps do not operat e when t he highbeam 'flas h' functi on is operat ed. If t he rot ary s wi tch i s in the headlamps pos it ion or AUTO pos it ion wi th the low beamlamps act ive, the xenon low beam wi ll remai n on when t he high beam 'flas h' funct ion i s operated.
The xenon headlamp sys t em i s cont roll ed by t he CJB usi ng a control modul e for each headl amp and an i gni ter. The cont rolmodules and t he ignit ers provide t he regulat ed power s upply requi red t o i ll uminate the xenon bulbs t hrough t hei r st art -upphas es of operat ion.
The xenon headlamp is a sel f cont ai ned unit located wit hi n t he headl amp as sembl y. The uni t compris es a refl ect or, t helens , a s hutt er controll er and t he xenon bul b, which as an as s embly i s known as the projector module.
The reflector provides t he mounti ng for t he xenon bul b which i s an i ntegral part of t he ignit er. The i gni ter l ocat es in anapert ure at t he rear of the refl ect or and is s ecured wi th 2 Torx s crews t o ens ure correct al ignment in the refl ect or.
A s hutt er is us ed t o change t he beam projecti on from l ow beam t o hi gh beam and vis a vers a. The s hut t er controller i s as olenoi d whi ch operat es t he s hut ter mechani s m vi a a l ever. W hen t he shut ter i s in the l ow beam pos it ion, it mas ks s omeof the light emi tt ed from the refl ect or, providi ng a defi ned low beam cut -off.
A t ouri st l ever mechani s m i s located on the right hand s ide of t he project or modul e. Thi s mechanis m moves a flap t o blankoff a porti on of the beam s pread to enabl e the vehicl e to be dri ven in opposi te dri ve hand markets wit hout applyingblanking decal s t o t he headlamp lens . The beam is changed by removing the cover at the rear of t he lamp ass embly andmoving a small lever locat ed at t he s ide of t he project or modul e.
The xenon bul b il lumi nat es when an arc of el ect ri cal current is es tabli s hed bet ween t wo electrodes wit hi n t he bulb. Thexenon gas s ealed i n t he bulb react s t o t he elect rical excit at ion and the heat generated by t he current flow to produce theblue/whi te li ght .
To operat e at ful l effi ci ency, the xenon bulb goes t hrough t hree s t ages of operat ion before ful l out put for cont inuousoperati on is achieved. The three phas es are; s t art -up phas e, warm-up phas e and continuous phas e.
In the st art -up phas e, the bul b requires an ini ti al hi gh vol tage s t art ing puls e of up t o 30000 volt s to est ablis h the arc. Thisis produced by t he i gni ters. The warm-up phas e begins once t he arc i s est abli shed. The xenon control modul es regulat et he supply to the bulbs t o 2.6A which gi ves a lamp out put of 75W . During t his phas e, the xenon gas begi ns to il luminat ebri ght ly and the environment wi thi n t he bul b s t abi lis es ens uring a cont inual current fl ow bet ween the el ect rodes. W hen thewarm-up phas e is compl et e, the xenon control modul es change t o cont inuous phas e. The s uppl y vol tage t o t he bulb i sreduced and the operat ing power requi red for conti nual operat ion i s reduced to 35W . The proces s from s tart-up t ocont inuous phas e i s complet ed in a very s hort t ime.
The xenon sys tem is cont roll ed by t he CJB, t he two xenon control modul es and the two ignit ers . The xenon controlmodules (one per headlamp) receive an operati ng vol tage from the CJB when the headlamps are s wit ched on. The modulesregulat e t he power s upply requi red t hrough t he phas es of s tart-up.
The ignit ers (one per headl amp) generat e t he ini ti al hi gh vol tage requi red t o es t ablis h t he arc. The ignit ers have i ntegralcoi ls whi ch generate hi gh vol tage pul ses requi red for s tart -up. Once t he xenon bul bs are operat ing, the ignit ers provi de aclos ed ci rcuit for regulat ed power s upply from the control modul es.
ADAPTIVE FRONT LIGHTING SYSTEM (AFS)

W hen t he i gni ti on is i n power mode 6, power i s s uppl ied, via t he i gni ti on rel ay in the BJB, to t he l ight cont rol module, t heheadl amp l eveli ng mot ors (or AFS motors if fit ted) and t o t he headl amp leveli ng module (or AFS cont rol module i f fi tt ed).
W hen t he l ight cont rol module rotary s wit ch is moved t o t he s ide l amp or headl amp pos it ion, a Local Int erconnect Net work(LIN) bus mes sage i s pas sed from t he li ght control modul e t o t he CJB for t he sel ect ed functi on. The CJB t hen is s ues a'l ights on' mes s age on the hi gh s peed CAN bus to the headlamp leveling modul e (or AFS control modul e i f fit t ed).
The headl amp l eveli ng module (or AFS cont rol module if fi tt ed) uses s i gnal s from t he front and rear height s ens ors toperi odi cal ly re-ali gn t he verti cal aim of t he headl amps to their opt imum pos i ti on.
